9-118.

For the rule

*y*= 6 + (−3)*x*: Homework Help ✎What is the

*y*-intercept?What is the slope?

The *y*-intercept is the point at which the graph intersects the *y*-axis. The graph will intersect the *y*-axis when *x* = 0.

Substitute 0 for *x* in the expression.*y* = 6 + (−3)(0)

*y* = 6

The slope is the value that *y* increases or decreases when *x* increases by one.

Create a table of values or sketch the graph on graph paper.

You should notice that from *x* = 0 to *x* = 1 the *y*-value decreases by 3. What is the slope?
