Recall that the slope-intercept equation of a line is of the form y=mx+b where m is the slope and b is the y-intercept. In our case, where are given the equation
[tex]y=\frac{1}{2}x-3[/tex]The question is asking for the value of b. To find this value, we simply compare this equation to the general form. We determine that m=1/2 and that b=-3. So the y-intercept of the line is -3.
