Question

in a simple linear regression, the following sample regression equation is obtained: yˆ= 424− 19x. a. interpret the slope coefficient.

Answer 1

Explanation:

comparing the equation

y=mx + c

y= -19x + 424

note that m is the slope and c is the intercept

so, since the slope is -19 it shows that the graph will be a negative graph.

I hope this helps.
