  1. 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 ✎

    1. y = 3 − 2x

    2. y = 2x

    3. y = 3

    4. y = -1/2x+ 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 = 2x + 0.
Follow the steps in part (a).

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

This is equivalent to y = 0x+3.
Follow the steps in part (a).
