So the triangle looks like this:The base is 8 and the height is 5.75, so the area is 23.3 . A
A key to solving this problem quickly is to draw a diagram. Notice that the y-intercept of the
first equation is –15 and the y-intercept of the second equation is 8.
To get an idea of the value of m, imagine that the second line has the same slope as the first
so that the two lines are parallel. Decreasing the slope of the second line would make the
line more horizontal, causing the two lines to intersect in the first quadrant, which does not
match the information given in the problem. However, increasing the slope of the second
line would make the line more vertical, causing the two lines to intersect in the third
