Bridgette -This equation might scare you because there are no x and y, but it is no different since you can use any letters for your variables.This is a linear equation (that is an equation for a straight line) and they made it easy for you by putting it in slope-intercept form.The y-intercept (or d-intercept in this case) is 7 which means when t=0, then d=7, so put a dot on the graph at the point (0,7).Next, starting at your dot, mark the next dot using the slope of the line which is 2. So go UP 2 and RIGHT 1.You should get something like this:Hope that helps
