The equation has two variables, y (longevity of car engine) and x (number of times oil changed).
This falls into the slope-intercept form of a linear function,which is , where b is the y-intercept (or in other words, the value of y when x is 0).
Comparing our equation to the slope-intercept form of a linear function tells us that the value 0.1576 is the y-intercept.
<em>It means </em><em>0.1576</em><em> is the expected longevity of a car engine when x is 0 (number of oil changed is 0). </em>This is answer choice A.
