4-62.

Use what you know about

*m*and*b*to graph each equation below without making a table. Show a growth triangle on each graph and label the*x*- and*y*-intercepts. 4-62 HW eTool (Desmos). Homework Help ✎*y*= 3 − 2*x**y*= 2*x**y*= 3*y*= + 3

Identify *m* and *b*.

*m* = −2, *b* = 3

Graph *b*, the *y*-intercept.

Use *m* to draw the rest of the line.

*x*-intercept = (1.5, 0)

*y*-intercept = (0, 3)

This is equivalent to *y* = 2*x* + 0.

Follow the steps in part (a).

*x*-intercept = (0, 0) *y*-intercept = (0, 0)

This is equivalent to *y* = 0*x*+3.

Follow the steps in part (a).
