Question from Lucinda, a parent: find the area of the figure formed by the line y=-5x+9 and the x-axis and y-axis. |
Hi Lucinda,
In the equation of the line let $x = 0$ to find the y-coordinate of the point where the line crosses the Y-axis. Let $y = 0$ to find the x-coordinate of the point where the line crosses the X-axis.
Draw a diagram!
The region described is a right triangle. What is its area?
