Answer:

7.5

Step-by-step explanation:

the slope m is a measure of the rate of change

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )

m = \frac{67.5-45}{9-6} = \frac{22.5}{3} = 7.5 ← rate of change

If AC = x + 5 and AB = 3x - 1... what is the length of BC?
Hatshy [7]
If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10     |subtract 2 from both sides
3x = 5x - 12      |subtract 5x from both sides
-2x = -12      |divide both sides by (-2)
x = 6
