if you put the points into the equation y2 - y1/x2 - x1 you'll end up with a zero in the denominator, which indicates a vertical slope. Basically the slope(m) is undefined
It's really easy to tell if your answer is going to be undefined if both the x values are the same (in this case they're both 9)
I did the math and I think it should be 67.5
One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.
-- One leg is 3 times the length of the other leg.
-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle.
I'll bet that if you look through the choices, you'll find one there.
Answer:
x = 5, x = -7
Step-by-step explanation:
If you mean find the roots, then x = 5 and x = -7
Because roots makes the equation equal to 0 and 5 - 5 = 0 and -7 + 7 = 0
