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)
