To be able to find the value of X, we have to cross multiply the two fractions then solve the equation.
As so,
6/4 = 15/x
Cross Multiply:
6 x X = 6x
4 x 15 = 60
We cross multiplied, now we can set up the equation:
6x = 60
Simplify: (Get X by itself)
Divide 6 on each side
6 / 6x = 60 / 6
x = 60 / 6
x = 10
Now we have the total of X! To check our answer, we can substitute X for 10 in the original equation.
As so:
6/4 = 15/10
6/4 = 1.5
15/10 = 1.5
Correct! Our answer is X = 10!

You could write this by going 63+42 or add 63 and 42
hope that's what you are looking for ;-)<span />
Answer:
Slope = Y2 -Y1 / X2 - X1
Slope = -1 -3 / 8 --8
Slope = -4 / 16
Slope = -1 / 4
To calculate the equation we fill in this equation:
(y - y1) = slope • (x -x1)
We only need to choose 1 point so we'll choose (-8, 3)
(y - 3) = -1 / 4 * (x --8)
So the Equation equals
y = -1 / 4 x -2 + 3
y = -1 / 4x +1
