7-65.

When Yoshi graphed the lines and

*, she got the graph shown at right.*

One of the lines at right matches the equation

, and the other matches. Which line matches which equation?Look at the

-intercepts, otherwise known as thein, to decide which line goes with which equation.line

: , line: Yoshi wants to add the line

to her graph. Predict where it would lie and sketch a graph to show its position. Justify your prediction.The slope of the line in part (c) is the opposite of the slope of the line in part (b). The

-intercepts are the same.Where would the line

lie? Again, justify your prediction and add the graph of this line to your graph.
