When x changes by 1 unit, by how much does y change?Step 1Recall that the least-squares line is of the form =abx, where a is the intercept and b is the slope.To find the slope of the line =15-15x, we rewrite it so that it has the form =abx.=15-15x=()()xNow we can identify that the slope of this least-squares line is ????????????
