Y=mx+b, where m is the slope and b is the y-intercept.

m=(y2-y1)/(x2-x1)=(4-8)/(-3-3)-4/-6=2/3 so

y=2x/3 + b, using either point, we can solve for the y-intercept...using (3,8)

8=2(3)/3 + b

8=2+b

b=6 so the line is:

y=2x/3 + 6 or more neatly

y=(2x+18)/3

Slope = (6 +9) / (2 +1) = 15/3 = 5

y = mx + b
-9 = 5(-1) +b
b = - 4

equation
y = 5x - 4

3. josephcarriveau says:

Y = m x + b

m : slope
b :intercept

m = -9 - 27/ 2 +2  = -9

y = -9 x + b

27  = -18  +b

b = 45

y = -9 x + 45

4. raynaesquivel says:

y = 6

Step-by-step explanation:

Find the y intercept (b) by plugging in (x,y) and m into y = mx + b

6 = 0 (-2) + b

6 = b

The equation will be  y = 0x + 6 OR y = 6

5. AgentPangolin says:

Slope = (2 -10) / (3 +1) = -8/4 = -2

y = mx + b
10 = -2 (-1) +b
b = 8

equation
y = -2x + 8

6. td0715 says:

Slope = (-9 -27)/(2 +2) = -36/4 = -9

y = mx + b
27 = -9(-2) + b
27 = 18 + b
b = 9

equation
y = -9x +9

The equation of the line is y=2/3x+6

9. $y=3x-3$

10. $y=8x+b$

Step-by-step explanation:

For question 9.

The given information is $m=3, b=-3$

The equation of a line is written as.

$y=mx+b$-----------(1)

Where m is the slope of the line and b is the y intercept.

Put the m and b value in equation 1.

$y=3x-3$

So, the equation of the line is $y=3x-3$

For question 10.

Given:

$m = 8$

The equation of a line is written as.

$y=mx+b$-----------(1)

Where m is the slope of the line and b is the y intercept.

Put the m value in equation 1.

$y=8x+b$

So, the equation of the line is $y=8x+b$.
