Question 265518: the following problem represents calculations of the slops. How do i solve for the variable?
70-y
____ = 0.5??
0-8
how do i figure out what variable " y" is?
can you please explain the methods that you would use to go about solving a question such as this? thank you very much
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
your equation is:

(70-y) / (0-8) = .5

simplify this to get:

(70-y) / (-8) = .5

multiply both sides of this equation by (-8) to get:

(70-y) = .5 * (-8)

simplify to get:

70 - y = -4

subtract 70 from both sides of this equation to get:

-y = -4 - 70

simplify to get:

-y = -74

multiply both sides by (-1) to get:

y = 74

confirm by substituting for y in your original equation to get:

(70 - 74) / (-8) = .5

simplify to get:

-4 / (-8) = .5

simplify to get:

.5 = .5 confirming the value for y is good.
