Parallel to 2x+y=-5
2x+y-2x=-5-2x
y=-2x-5
y=mx+b
Slope: m=-2
As the line is parallel must have the same slope:
m=-2
And it has an x-intercept of 2: when x=2, y=0→Point: P1=(2,0)=(x1,y1)
x1=2, y1=0
y-y1=m(x-x1)
y-0=(-2)(x-2)
y=-2x+4
In standard form:
y+2x=-2x+2x+4
2x+y=4
The equation of the line, in standard form, that passes through the origin and is parallel to x+y=6 is x+y=0
Paralell to 2x+y=-5
means it has same slope
means it is in form
2x+y=c where we have to find c
convert to slope intercept
minus 2x both sides
xint of 2
xint is where th eline crosses the x axis or where y=0, x=2
2(2)+0=c
2(2)=c
4=c
the equation is 2x+y=4
1. [tex]-5x+3y+44=0[/tex]
2. [tex]2x+y-2=0[/tex]
3. [tex]2x+y-4=0[/tex]
Step-by-step explanation:
Standard form of a line is [tex]Ax+By+C=0[/tex].
If a line passing through two points then the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope, i.e.,[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex].
1.
The line passes through the points (7,-3) and (4,-8). So, the equation of line is
[tex]y-(-3)=\dfrac{-8-(-3)}{4-7}(x-7)[/tex]
[tex]y+3=\dfrac{-5}{-3}(x-7)[/tex]
[tex]y+3=\dfrac{5}{3}(x-7)[/tex]
[tex]3(y+3)=5(x-7)[/tex]
[tex]3y+9=5x-35[/tex]
[tex]-5x+3y+9+35=0[/tex]
[tex]-5x+3y+44=0[/tex]
Therefore, the required equation is [tex]-5x+3y+44=0[/tex].
2.
We need to find the equation of the line, in standard form, that has a y-intercept of 2 and is parallel to [tex]2 x + y =-5[/tex].
Slope of the line : [tex]m=\dfrac{-\text{Coefficient of x}}{\text{Coefficient of y}}=\dfrac{-2}{1}=-2[/tex]
Slope of parallel lines are equal. So, the slope of required line is -2 and it passes through the point (0,2).
Equation of line is
[tex]y-2=-2(x-0)[/tex]
[tex]y-2=-2x[/tex]
[tex]2x+y-2=0[/tex]
Therefore, the required equation is [tex]2x+y-2=0[/tex].
3.
We need to find the equation of the line, in standard form, that has an x-intercept of 2 and is parallel to [tex]2x + y =-5[/tex].
From part 2, the slope of this line is -2. So, slope of required line is -2 and it passes through the point (2,0).
Equation of line is
[tex]y-0=-2(x-2)[/tex]
[tex]y=-2x+4[/tex]
[tex]2x+y-4=0[/tex]
Therefore, the required equation is [tex]2x+y-4=0[/tex].

X+y=0
-2x+y=2
-2x+y=-4
The general equation of the line is ⇒⇒⇒ y = mx + c
where: m is the slope of the line , c is constant
The given line is 2x + y = -5 ⇒⇒⇒ ∴ y = -5 - 2x
The slope of the given line = -2
The required line is parallel to the given line . So, it have the same slope
∴ m = -2
∴ The general equation of the line will be ⇒⇒⇒ y = -2x + c
to find c we need a point on the line
x-intercept of 2 which mean the line pass through (2,0)
substitute with (2,0) to find C
∴ 0 = -2*2 +c ⇒⇒⇒ c = 4
The required line is ⇒⇒⇒⇒ y = -2x + 4
OR 2x + y = 4
Y=2x-5 because parallel means keep the slope the same and the formula is y=mx+b b is y and y is -5 so your answer is y=2x-5
The equation of a line is represented by the affine function y = mx + b, where m represents the slope, b the y-intercept, x and y the coordinates of a point.
First, we need to transform 2x + y = -5 to the y = mx + b form.
First, let's subtract 2x from both sides to have the y on the left side, and all the other variables and numbers on the right side.
2x + y - 2x = -5 - 2x
y = -2x - 5
That's the standard form of the equation. Now we need to find a parallel.
2 parallel lines have the same slope so m = -2. So we get y = -2x + b
By hypothesis, the line have an x-intercept of 2, which means that for y=0, x = 2. Let's insert those coordinates into our equation to find the y-intercept.
y = -2x + b
0 = -2 * 2 + b
0 = -4 + b
Add 4 on both sides to have b on a side and its value on the other
0 + 4 = -4 + 4 + b
4 = b
We found the y-intercept.
So, the equation of the parallel line is y = -2x + 4
I've added a picture of the graphical representation of both lines.
Hope this Helps! 🙂

To become parallel, equations need to have the same slope for the x-axis. To do that, let's convert the equation to Slope Intercept Form.
2x + y = -5
Subtract y from both sides
2x = -y - 5
Divide both sides by 2.
x = -1/2y - 5/2
The slope is -1/2. Knowing this, we can make this equation.
x = -1/2y + 2
Now, we have to convert that into Standard Form.
x = -1/2y + 2
Add 1/2y to both sides.
x + 1/2y = 2
Multiply everything by 2.
2x + y = 4
