Question

Please help with 17 and/or 18

Answer 1

7.
`y = 3x + 10`

8. Correlation: The more they spend in advertising dollars, the more sales they will get.

Explanation:

The slope-intercept form is y=mx+b. The mx is the slope and the Y is the y-intercept.

All you have to do here is add the 3x to 10 so that the y is isolated.

y = 3x + 10

A correlation is like an "If... then" statement. But it's more written like:

"The more/less they do this, the number of this will increase/decrease."

The more they spend in advertising dollars, the number sales will increase.

Answer 2

Slope Intercept Form: y=3x+10

Slope: 3

y: 10

Explanation:

y-3x=10 Add 3x to both sides. The y has to be isolated.

So it is y=10+3x So we have to reorder it so y=3x+10
