We have this equation for the slope is: y=mx+b which m is the slope and b is the y-intercept, so we have y=20-15x or y=-15x+20, and we already know that the slope is -15 and y-intercept is 20. As a result, the student's error is that he thinks that 20 is the slope because it is the first number. Hope it help!

The area of a triangle is 22 yd with a base of 8 years. What is the height, in yards?
cluponka [151]
The area of a triangle can be found using the formula 1/2*b*h

We can substitute what we know in now, 22 = 1/2*8*h

22 = 4*h
22 = 4*5.5

The answer would be 5.5 yards

I hope this helps!
