Question

90 POINTS I WILL GIVE BRAINLIEST! - If a line with the equation y = x is dilated by a factor of 2 what is the equation of the resulting line? If it is then moved three units up, what is the equation of the resulting line? - I want to say that the equation does not change, is that correct or am I missing something?

Answer 1

Answer:

Step-by-step explanation:

y=x

dilating an equation means you multiply it by constant a

y=x the  y=ax after dilation (a=2)

y=x

y=2x

If it is then moved three units up: means you add constant b (b=3)

y=2x+3

Answer 2

Answer:

y=2x+3
