Question

find the value of y so that the line is passing through (9, 0) and (3, y) has a slope of -1/2

Answer 1

\[Slope = \frac{y_2 - y_1}{x_2 - x_1}\]

Answer 2

so how do i plug in the y?

Answer 3

Put the given values in the formula:

\[\huge \frac{-1}{2} = \frac{y - 0}{3-9}\]

So, can you now solve it for y?

Answer 4

so its -1/2 + y/6

Answer 5

How??
Do it clearly??

Answer 6

oh my bad i meant to put -1/2 = y/6

Answer 7

-1/2 = y/-6

Answer 8

Yes now you are right..
Multiply by (-6) both the sides and tell me what you get?

Answer 9

6/-12 = y

Answer 10

Solve it once again..
