Answer: y = -1/-2x + 3 or y = 1/2x +3
Explanation:
you first find the y intercept of the equation y = mx+b
to do this you go to 0 and find count up or down until it crosses the y axis(3).
from there you find your slope count up or down and left and right
slope formula is m=rise over run (-1/-2).
then you plug in your numbers to slope intercept form.
