y=-5/2-22
because since y= m(slope)x + b
and we already have the slope, to find b we need to plug in (-6 (for x),- 7 for y)
so -7= -5/2(-6) + b
and then we multiply -5/2 times -6 which equals to 15 so then we do
-7= 15 + b
and then we subtract 15 from -7 (-7 -15)
to give us -22= b
and then we have the full eq of y= -5/2 -22
hope this helps!
