1.Find the equation of the line that cntains the pont (5, -1) and has slope -1/2

2.find the equation of the line that passes through the points (-2,1) and (1,-5)

**Reiny**, Monday, October 26, 2009 at 4:56pmEasiest way, since you don't specify which form you want your equation in.

(based on the fact that for Ax + By = C 0, the slope is -A/B)

1. Slope = -1/2

so the equation is x + 2y = C

plug in point, 5 - 2 = C

C = 3

so ..... x + 2y = 3

from there you can change it to any form they ask for.

try the second one the same way.
