Kara used the linear model y=45,000 + 0.05x to predict her total salary from achieving total sales of x.

Intercept the slope and y-intercept in terms of her salary and sales

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add. 05 to her salary

Step-by-step explanation:

y = 45,000 +.05x

Rewriting as

y =.05x + 45,000

This is in slope intercept form (y=mx+b) where m is the slope and b is the y intercept

.05 is the slope and 45,000 is the y intercept

45,000 is the starting salary with zero sales

.05 is the amount multiplied by the number of sales that is added to her salary

For each sale we add. 05 to her salary
