Question

Can someone help me with this? Find x or y. Remember that each pair of points lies on a line with the given slope.
(4,y), (2,4y); slope 6
(2,4) , (x,8); slope -2

Answer 1

Do you remember your formula for finding slope?

\[\LARGE m = \frac{y_1-y_0}{x_1-x_0}\]

Answer 2

Yeah except my teacher showed it to the class as m=y2-y1/x2-x1

Answer 3

Same thing. :P

Plug in your values for that and see what you get.

Answer 4

ok thanks.
