y + 6 = 9(x − 8)
Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answer 1

y = 9x -78

Explanation:

You want the equation y + 6 = 9(x − 8) written in slope-intercept form.

Solution

Solve for y and simplify.

y +6 = 9x -72 . . . . . . . . eliminate parentheses

y = 9x -78 . . . . . . . . . subtract 6

Additional comment

The given equation is written in point-slope form. It has a slope of 9 and goes through the point (8, -6).

Slope-intercept form is ...

y = mx +b

where m is the slope and b is the y-intercept.
