A is the correct answer I hope that helps :)
It’s A .
Explanation : an app I would use to help on math would be Photomath ! It would help out on math problems by taking a picture of the problem !! I hope this helped :)
Step-by-step explanation:
We have been given the linear regression equation for a data set is y=-2.8x+70.8 where y is the temperature in degrees Fahrenheit and x is the number of hours since 8 am.
We can see that our given line is in slope-intercept form: , where, m = Slope of line and b = y-intercept.
Upon comparing our given equation with slope intercept form we can see that the slope of the equation (m) is -2.8. The slope represents that temperature is dropping at a rate of 2.8 Fahrenheit per hour after 8 am.
I’m not sure if I did my math correct but I got 1x
