a. The y-intercept is the constant in the linear equation:
—5
The slope is the coefficient of x in the linear equation:
0.75
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 $$\displaystyle\Rightarrow$$ Slopes downwards
c. Evaluate the given equation for two values of x.
Graph the two points.
Draw a line through the two points:

Results:
a.-5,-0.75
b.Slopes downwards
c.See graph
