The slope formula is the difference of the y values over the difference in the x values. We have a slope, so we will fill in the formula with what we have and then solve for x: 
. Multiply both sides by x-10 to get rid of the fraction. -2(x-10) = 4. Distribute to get -2x+20=4 and -2x = -16. That gives us an x value of 8.
Answer:
x=0,
Decimal form,
x=0,1.30766048......
Step-by-step explanation:
x=
x-
=0
(take x as a common factor)
x(-
)=0
So,
x=0 and -
=0
for -
=0
(add for both sides)
=
x= (multiply 3 by 2)
x=
So,
x=0,
