4-77.

Determine the slope and *-*intercept for each line.

There are many methods possible to accomplish this.

1) Slope and -intercept can be identified from the Slope-Intercept form of the equation.

This form is often written as

*where*

*is the slope and*

*is the*

*-intercept.*

2) Alternatively, you could calculate the

*-intercept (where*

*) and calculate*

**any**other point (by letting

*for instance) and then calculate the slope from those two coordinates.*

Solving for

*y*will place this equation in Slope-Intercept Form.

This equation is written in Slope-Intercept form, but it has been rearranged.

Its form is more like

This equation will be easier to read if the fraction is separated into two terms.
