Aline with slope of -3 passes through the points ( x , -6 ) and ( -2 , 6 ). what is the missing x-coordinate?

We can use our formula, y2-y1/x2-x1 to get our answer. We have: 6-(-6)/-2-x = -3. We can simplify this to get 12/-2-x = -3. We multiply both sides by -2-x to get 12 = -3(-2-x). That gets us 12 = 6+3x. Subtract 6 from both sides and get 6 = 3x. Last, we divide both sides by 3 to get x = 2. Hope this helped.
