Question

what is the slope of the line passing through the points A(-5,7) andB(4,7)

Answer 1

slope = difference in the y-values/difference in x-values

Answer 2

ok so how do u do it

Answer 3

what is the difference in y-values?

Answer 4

-9

Answer 5

No. What are the two y-values?

Answer 6

-5 and 4

Answer 7

Those are the x-values. The y-values are 7 and 7. What is the difference?

Answer 8

0

Answer 9

Yes. So you have a fraction with 0 in the numerator, so the entire fraction equals 0. So the slope is 0.

And a line with a slope of 0 is always a horizontal line.

If you plot the 2 points, you will see that it is a horizontal line (whose slope is 0).

Answer 10

so all horazonal lines are 0 ?

Answer 11

yes

Answer 12

ok thanks

Answer 13

Welcome.

Now try doing this one:

Find the slope of the line passing through the points (-2,4) and (3,-8).

Answer 14

y= -4
x=-5

Answer 15

You take the Difference between the two y-values:

The two y-values are 4 and -8; the difference is -8-4 = -12

Take the difference between the two x-values:

The 2 x-values are -2 and 3. The difference is 3 - (-2) = 3 + 2 = 5

Slope = -12/5.
