Find the value of r so that the line that passes
through each pair of points has the given slope. (6, r), (3, 3), m= 2

The value of r is 9

Step-by-step explanation:

- The slope of a line whose endpoints are and

is

- A line passes through points (6 , r) and (3 , 3)

- The slope of the line is m = 3

- We need to find the value of r

- Let and

- Let and

∵ m = 2

- Substitute these values in the rule of the slope

∴

∴

- Multiply both sides by -3

∴ - 6 = 3 - r

- Add r to both sides

∴ r - 6 = 3

- Add 6 to both sides

∴ r = 9

* The value of r is 9

d is correct
