7-9.

Write the equation of the line with *x-*intercept (–4, 0) and y-intercept (0, 9). Homework Help ✎

Use the slope-intercept form of a line (*y* = *mx* + *b*).

Substitute the *y*-coordinate of the *y*-intercept for *b* in the equation.

Find the slope using any method you like, then substitute that value for *m* to finish writing the equation.
