Answer:
-5/7
Step-by-step explanation:
Find the change between the two x values, which is seven
Find the change between the two y values, which is -5
With slopes, the y always goes over the x, making your answer -5/7
Answer:
We will add 64 to both sides.
x=8±√20
Step-by-step explanation:
Here we are given the equation:

Now we take half of the coefficient of x and add it to x.
Coefficient of x is 16, half of 16 is 8.
Also we add square of 8 to both sides.
So new equation becomes:

Completing the square:

NOw let us simplify it to get the value of x.
Taking square root on both sides:

Bringing 8 to the right side:
x=8±√20
