ok so can u help me

Answer 4

y = 1/2x - 3

-3 is your y intercept.
to find you x intercept, sub in 0 for y...
0 = 1/2x - 3
-1/2x = -3
x = -3/(-1/2)
x = -3 (-2) = 6 <-- your x intercept.

your slope is 1/2....put a dot on the y axis at -3, go up 1 and over 2, then up 1 and over 2.

It should look like this...
