Question

What am I doing wrong?

Answer 1

Im afraid I cant make out the document bu this is how to  solve it:-

First find the slope of the line

slope = rise / run =  (7-2) / (5- - 1) = 5/6

Now use the point-slope form of equation of a straight line:-

y - y1 = m (x - x1)  where m= slope and (x1, y1) is a point on the line. Use the point (-1, 2):-

y - 2 = (5/6) (x + 1)

multiply through by 6:-

6y - 12 = 5(x + 1)

6y - 12 = 5x  + 5

-12 = 5x - 6y + 5

-17 =  5x - 6y

Flipping it over:-

5x - 6y = -17

5x - 6y = -37
