2-70.

Draw accurate graphs of $y=2x+5$, $y=2x^2+5$, $y=\frac{1}{2}x^2+5$ on the same set of axes. Label the intercepts. Homework Help ✎.

1. In the equation $y=2x+5$, what does the 2 tell you about the graph?

This is in the form $y=mx+b$. What does m stand for?

2. Is the 2 in $y=2x^2+5$ also the slope? Explain.

Is this in the form, $y=mx+b$?

2 is the stretch factor. This is a curve, so it does not have a constant slope.
