It moves the graph 5 steps downwards on the y axis.
Answer:
x = 4
Step-by-step explanation:
3 + x = 7 ( isolate x by subtracting 3 from both sides )
x = 7 - 3 = 4
For this, you have to plot the points on the graph. where it says right hand height, you go down to that number on the x axis (horizontal) and then up to the correct number for right foot length (vertical)
