10-19.

The equation is already in slope-intercept ( *y = mx + b* ) form.

*m* = slope*b* = *y*-intercept

*y*-intercept = (0, −7)

Solve the equation for *y*.

If you are having trouble, refer to part (a).

Start by finding the slope.

Substitute a point into the equation

*y = mx +b* and solve for *b*, the *y*-intercept.

4 = 2(8) + *b*

4 = 16 + *b*

−12 = *b*

Slope = 2*y*-intercept = (0, −12)
