y = -3/2x + 15/2
This equation is a slope-intercept equation for the line that passes through the points (4,8) and (-2,-7). The slope of the line is -3/2, which is found using the rise/run formula (change in y/change in x). The y-intercept (the point at which the line crosses the y-axis) is 15/2, which is found using the point-slope formula.
