What is the total area of the figure?

If you cut the figure in half, it makes 2 shapes, one which is 3x5 and one which is 3x3 so the total area is 15+9 or 24m^2

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
