Question

The equation of the line of best fit of a scatter plot is y = 8x − 1. What is the slope of the equation?

Answer 1

8

Explanation:

I just took the test.

Answer 2

The slope is 8. In an equation of a line, y =mx + b the m is the slope and the b is the y-intercept. In your equation, you have y = 8x -1
If we look at y = mx + b and y = 8x -b we can see the similarities

y = mx + b
y = 8x - 1

m = slope = 8
b = y-intercept = -1

Slope = 8
