SOLUTION: A line has a slope of 7. For each pair of points that are on the line (3,-6) and (7,y) , use the slope formula to find the missing coordinate. I know that y=22 but I do not know

Question 178964: A line has a slope of 7. For each pair of points that are on the line (3,-6) and (7,y) , use the slope formula to find the missing coordinate.
I know that y=22 but I do not know how or the steps used to get the answer y=22

Note:

is the first point (3, -6) and

is the second point (7, y)

Start with the slope formula

Plug in (the given slope) , , , and (the coordinates of the given points)

Rewrite as

Subtract

Multiply both sides by 4

Multiply

Subtract 6 from both sides.

Combine like terms.

So the answer is
