Suppose the linear regression line y=2.1x+130 predicts sales based on the money spent on advertising. if x represents the dollars spent in advertising, and yea represents the company sales in dollars, about how much can the company expects in sales if it spends $150 in advertising

Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.

Linear regression represents the relationship between two variables. the value of y depends on the value of x.

x represents the dollars spent in advertising and y represents the company sales in dollars.

We need to find out sales y when $150 spends on advertising.

Plug in 150 for x and find out y

y = 2.1 x + 130

y = 2.1 (150) + 130

y= 445

The company expects $445 in sales
