Question

The equation of the line of best fit of a scatter plot is y = −3x + 2. What is the slope of the equation?

−3
−2
2
3

Answer 1

-3

Explanation:

Hello!

The equation of a line is written in the form:
`y = mx + b`

• y = output
• m = slope
• x = input
• b = y-intercept

Given our equation:
`y = -3x + 2`

• m = -3
• b = 2

Therefore, the slope is -3.
