CPM Homework Help : MC2 Problem 6-48

Use the graph below to add points to the table below.

$x$
$y$

Step 1:

For each point, find its $x$ -coordinate and its $y$ -coordinate and record the two numbers next to each other in the table.

Answer:

Write the rule in words.
Hint (a):
Notice that for every $1$ the $x$ -value increases, the $y$ -coordinate decreases by $2$ . Also take into account where the $y$ -intercept is.
Answer (a):
Multiply $x$ by $−2$ and then add $6$ .
Explain how to use the table to predict the value of $y$ when $x$ is $–8$ .
Hint (b):
Extend the pattern in the table. Answers may vary.
