Question

Consider the y-intercept. The equation of your model is y = 8.39x. The y-intercept is zero. Should it be? Explain. ​

Answer 1

yes, the y-intercept should be 0.

Explanation:

The b in this slope-intercept equation is 0, so the y-intercept is 0.

Another way to figure out the y-intercept is to set x to 0; the resulting y-value is the y-intercept:

y = 8.39(0)

y = 0 so the y-intercept is 0.
