When yoshi graphed the lines y=2x+3 and y=2x-2, she got the graph shown at right ?

When Yoshi graphed the lines y = 2x + 3 and y = 2x − 2, she got the graph shown at right.

One of the lines at right matches the equation y = 2x + 3, and the other matches y = 2x − 2.  Which line matches which equation?

i)   y = 2x – 2  

when x = 0, y = 2(0) - 2 = -2; when y = 0, 2x = 2 and x = 1.

Therefore, the line matching the equation y = 2x - 2 is the line passing through the points (0, -2) and (1, 0).

ii) y = 2x + 3

if x decreases by 4 then y increases by 10
