It depends what type of equation you are trying to solve for. For slope intercept form (y=mx+b) - pick two coordinates and find the slope using the slope formula; y2-y1 over x2-x1. - the y-intercept is usually found in (0, b) form. After you have found the slope and the y - intercept you can finally plug in your numbers to match the formula. Here is an example: - My two coordinates on the line are (0,8) and (-1,5) - 8-5 over 0--1 = 3 over 1, or 3 is my slope. - To find the y intercept look for the pair that is found in (0,b) form which in this case is (0,8) so my y intercept is 8. You found your slope and y intercept so your equation is y = 3x + 8 Hopefully this helped! This is how you find an equation for slope intercept form! If it is any other formula it is basically the same general steps.
< xcy ≅ < xby
step-by-step explanation:
in δcax and δbax,
ac ≅ ab (given)< cax ≅ < bax (given)ax ≅ ax (common side)
so, δcax ≅ δbax (side-angle-side or sas)
since δcax ≅ δbax, we can conclude < acx ≅ < abx
in δacy and δaby,
ac ≅ ab (given)< cay ≅ < bay (since < cax ≅ < bax is given and xy is the extension of line ax)ay ≅ ay (common side)
so, δacy ≅ δaby (side-angle-side or sas)
since δacy ≅ δaby, we can conclude < acy ≅ < aby
now,
< acy ≅ < aby
=> < acx + < xcy ≅ < abx + < xby
=> < acx + < xcy ≅ < acx + < xby (since < acx ≅ < abx already proved above)
subtracting < acx from both sides, we get
< acx + < xcy -< acx ≅ < acx + < xby -< acx
cancelling out < acx and -< acx from both sides, we get
< xcy ≅ < xby (proved)
