, the slope is .
The slope you want for the line perpendicular to must be . The slopes for perpendicular lines in a plane must be negative reciprocals.
Using SLOPE-INTERCEPT FORM, you want an equation and you do not yet know b. You know that the line must pass through (-9,3).
Substitute the coordinate values.
-
Equation in slope-intercept form still, is .
Convert that into standard form.
