Question

Find an equation of the line containing the given pair of points. (-5,-2) and (-3,-1). The equation of the line in slope-intercept form is y=.
Here is what I came up wiyh: y=1/2x-1/2. Is this correct?
I am confused on this problem. Could someone please help?
Thanks.

Answer 1

Your slope is correct, so
y = (1/2)x+ b
use point(-3,-1)
-1 = =-3/2 + b
b = -1 + 3/2 = 1/2

so y = (1/2)x + 1/2

check with other point
LS = -2
RS = (1/2)(-5) + 1/2
= -5/2 + 1/2 = -2
= LS

you had a sign error somewhere.
