Answer:
a)?
b) y=2x-2
Step-by-step explanation
you have to put it in the form of y=mx+c
first we figure out m, m is the gradient, the gradient is the slope
and he slope hits -2 so now we have y=-2x+c
now for c, c is the x line, and the slope hits 2 on the x line
now we have y+-2x+2
hope this helps :)
