2.Write the equation of a line in slope-intercept form that passes through the points ( -2, 5) and (-2, 11). Do not use any spaces. Slope should be a reduced improper fraction.

**Reiny**, Friday, May 25, 2012 at 9:35pm1. You know the slope is -1/4, so the equation must be

y = (-1/4)x + b

but the point (8,-1) lies on it, so

-1 = (-1/4)(8) + b

-1 = -2 + b

1 = b

y =(-1/4)x + 1

2. the slope is (11-5)/(-2+2) = 7/0

ahhh, the slope is undefined, so it must be a vertical line, and without any more work we can see the equation is

x = -2
