CPM Homework Help : GC Problem 1-43

Using graph paper, draw a pair of $xy$ -axes and scale them for $-6 \leq x \leq 6$ ( $x$ -values between and including $−6$ and $6$ ) and $−10 \leq y \leq 10$ ( $y$ -values between and including $−10$ and $10$ ). Complete the table below, substituting the $x$ -values (inputs) to find the corresponding $y$ -values (outputs) for the rule $y = x + 2$ . Plot and connect the resulting points.

x (input)	$−4$	$−3$	$−2$	$−1$	$0$	$1$	$2$	3	4
y (output)

Answer:

Line has a $y$ -intercept of $(0, 2)$ and an $x$ -intercept of $(− 2,0)$ .

x (input)	$−4$	$−3$	$−2$	$−1$	$0$	$1$	$2$	3	4
y (output)	$-2$	$-1$	$0$	$1$	$2$	$3$	$4$	$5$	$6$

Coordinate axes, point on positive y axis, & point on negative x axis, each the same distance from the origin, increasing line passes through both points.
