So just remember tha tyou can do anything to an equation as long as you do it to both sides (except divide by 0) so
-7.12=-4.8+x
add 4.8 to both sides since -4.8+4.8=0 so it cancels
4.8-7.12=x
simplify
4.80-7.12=-2.32
-2.32=x
the naswer is C

Answer:
y = -2x + 1
Step-by-step explanation:
y = mx + b (m is the slope and b is the y-intercept)
y = mx + 1
Equation for slope: 
(0,1) (1,-1)
=
= -2
y = -2x + 1
-(x-20)
Basically it’s the same as your other question but your not adding twenty!
