Answer:

$445

Step-by-step explanation:

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

To paint a house, a painting company charges a flat rate of $500 for supplies plus $50 for each hour of labor. What is the slope

Nataly_w [17]

The slope of the line is 50. You can try looking at the equation, which is

y=50x+500

500 is your y-intercept, and is where the cost starts.

50 is your slope, since the cost goes up by $50 every time.

x is how many hours, which determines how many $50s there are.

I hope this helps. All in all, the slope is 50.
