3-76.

For the rule $y=−2x+1$, calculate the $y$-values that complete the table below.

 IN (x) –4 –3 –2 –1 0 1 2 3 4 OUT (y)
1. Graph your rule on a set of axes. Be sure to create a complete graph. If necessary, see the Math Notes box for this lesson to review what makes a graph complete.

2. Describe your resulting graph. What does your graph look like?

Does the line decrease or increase as $x$ gets larger?
Is it vertical, horizontal, or slanted?
