when y=20, 2x+5 is equal to it, since y=2x+5
2x=15
x=7.5

A simple linear equation has been fit to 15 (x, y) pairs
with a slope of 2 units and an intercept of 5 units. What is
the predicted value when the independent variable is
equal to 20?
m, or slope: 2
y-intercept: 5
Predicted value: y
Independent variable: x
Linear equation: y = mx + b
We then get:
