Literally just plug it in
6(7) + 5(-4) - 42 = 0
42 -20 -42 = 0
-20 = 0
Not a solution.
5^-3 is 1/125
The negative in the exponent makes it so there is a 1 over the problem if there was no negative. When you have a negative in the exponent, the answer will be the reciprocal (opposite) of the question with no negative.
For example,
9^2 = 81
9^-2 = 1/81
Midpoint is (X1+X2)/2 and (Y1+Y2)/2. Therefore it would be (10+8)/2 Which is 9.
And (2-3)/2 which is -1/2. THE MIDPOINT WOULD BE (9,-1/2)
