a. The y-intercept is the constant in the linear equation:

-3

The slope is the coefficient of x in the linear equation:

0

b. If the slope is positive, then the graph slopes upwards. If the slope is negative, then the graph slopes downwards. If the slope is 0, then the graph is horizontal.

Slope = 0 \(\displaystyle\Rightarrow\) Horizontal

c. Evaluate the given equation for two values of x.

Graph the two points.

Draw a line through the two points:

Results:

a.-3,0

b.Horizontal

c.See graph
