Im not sure what you do with this question

Answer 1

Hi Jasmine,

This equation is the equation of a line with a slope of 3.5 and a y intercept of 4.6

 

The y intercept is the point at which this line crosses. or intercepts, the y axis.

 

The y intercept becomes the value of the equation yhat = 3.5x + 4.6 when x=0

 

yhat = 3.5 * 0 + 4.6 = 4.6

 

Hope this helps
