Question

Create a table for the equation with a y-intercept of 15 and a slope of -5. What is the output when x is -10?

-6 ?​

Answer 1

The output is 65 when x is -10.

Explanation:

y=mx+b is the easiest form to understand visually what the slope and intercept is.

m is the slope and b is the y-intercept. Replace both of these variables respectively with their appropriate values. In this case, the slope (m) is -5 and y-intercept is 15.

Equation looks like this: y=-5x+15

What is the output when x is -10? Replace x with 10, and your output is the y value.

`y=-5(-10)+15\\y=50+15\\y=65`
