CPM Homework Help : AC Problem 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 ✎
1. y = 3 − 2x
2. y = 2x
3. y = 3
4. y = + 3

Step 1(a):

Identify m and b.

Step 2(a):

m = −2, b = 3

Step 3(a):

Graph b, the y-intercept.

Step 4(a):

Use m to draw the rest of the line.

Intercepts:

x-intercept = (1.5, 0)
y-intercept = (0, 3)

Hint (b):

This is equivalent to y = 2x + 0.
Follow the steps in part (a).

Answer (b):

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

Hint (c):

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

Hint (d):

Follow the steps in part (a).
