Answer:
plug each half of the ordered pair into the variable term. (x,y)
Step-by-step explanation:
For example (---,20) y=5x 20=5x divide by 5 on both sides 20/5= 4 x=4
Range is the set of all output values of the dependent variables.
X=2
y=-2-2x=-2-4=-6
so you choose a
5x + 45
you multiply the 5 & x, then the 5 and the 9.
