Graph the line that passes through the points (-2, 0) and (4,−9) and determine the equation of the line.

Answer 1

(-2,0) and (4,-9) have a linte through them with slope = (-9-0)/(4--2) = -9/2 = (y-0)/(x+2)

slope = "rise over run" = difference in y divided by difference in x

y = (-9/2)(x+2) = (-9/2)x -9

y = -9x/2 - 9 in slope intercept form

or

9x +2y = -18 in standard form
