Using the same triangle as above, calculate the area of the triangle. You must show TWO methods for calculating the area of the
triangle. Round both answers to nearest tenth. Hint: you should be using the same values you provided in question 3 and you can use any values you calculated in question 3 as well.
Use the slope formula y2-y1 m=--------- x2-x1 (rise-->y over run-->x) so it would be 9-5 m=------- 1-10 and that would simplify to 4 ---- -9 and that would be your slope.
