Answer:
y=-2/4x + (-4.5)
Explanation:
so first we look for the slope which is rise/run.
start with the lower point and count up two.
the count to the left and you have -2/4, thats your slope.
then you chose one point, like (1,-5)
so either using point slope form y-y1=m(x-x1) or standard form y+mx+b
im going to use standard form
plug in your points like so:
y= -2/4x +b
-5= -2/4(1) +b
-5 = -1/2 + b
-5+ 1/2 = b
-4 1/2 =b
so y should equal
y=-2/4x + (-4.5)
im not sure but i hope this helps a bit
