Answer:
7. [tex]y = 3x + 10[/tex]
8. Correlation: The more they spend in advertising dollars, the more sales they will get.
Step-by-step 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.
