Question

What is the slope of the line that contains the points (0, 3) and (8, -3)?

A. -4/3
B. -3/4
C. 4/3
D. 3/4

Answer 1

Are you familiar with the slope formula?

\[\Large m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\]

Answer 2

Kinda, I haven't done slopes for a while..

Answer 3

the slope is the ratio of change in y with change in x as indicated by the formula above

Answer 4

a?

Answer 5

Im kind of confused on it,.

Answer 6

what are the y coordinates of the points (0, 3) and (8, -3)

Answer 7

3 and -3?

Answer 8

subtract the two y coords:

y2 - y1 = (-3) - (3) = -6

-------------------------------------------------------

then you subtract the x coords in the same order

x2 - x1 = (8) - (0) = 8

-------------------------------------------------------

Then you divide the y result by the x result: -6/8 = -3/4

notice how it's y over x (not x over y)

Answer 9

Yes. So then it would be B.

Answer 10

correct
