Question

Choose the correct slope of the line that passes through the points (0, -5) and (0, 7.5).

3/2
2/3
-3/2
-2/3

Answer 1

Subtract the y coordinates. What do you get?

Answer 2

to find the slope:\[y _{2}-y _{1}\over x _{2}-x _{1}\]

Answer 3

just do y2 - y1 divided by x2 - x1

Answer 4

Yes, once you have that, you’ll have a fraction, which is your answer.

Answer 5

\[7.5-(-5)\over0-0\]

Answer 6

work that :)

Answer 7

I Know,i just can figure out the answer

Answer 8

There has to be a typo somewhere since none of the answer choices listed are actually the true answer.

Answer 9

its 7 1/2 not 7.5

Answer 10

so the two points are (0, -5) and (0, 7 1/2) ???

Answer 11

yeah i think

Answer 12

oh that's (7.5, 0)

Answer 13

that might explain your error

Answer 14

yea

Answer 15

The answer is infinity. Unless there’s a mistake in the typing here.

Answer 16

Infinity, or error.

Answer 17

So the two points should be

(0,-5) and (7.5, 0)

you can write them as

(0,-5) and (7 1/2, 0)

or as

(0,-5) and (15/2, 0)

Answer 18

Why would you write them as 7 1/2 , that’s a completely different lesson

Answer 19

an old useless grade 8 math lesson of proper fractions. never use them. only use improper. or if you can, decimals. I’m just saying, proper fractions could get you docked, depending on where you learn.

Answer 20

what about this one what would be the slope for this

Answer 21

2
-2
1/2
or
-1/2

Answer 22

can you list two points that lie on that line?

Answer 23

[0,-3],[-1.5,0]?

Answer 24

good, do you know how to use these points to find the slope?

Answer 25

subtract then divide?

Answer 26

-2 :) got it

Answer 27

yes that's correct, nice work

Answer 28

thanks so muchh!!!!
