Question

What is the slope of the line passing through the points (1, –5) and (4, 1)?

A. 2


B.-5/4


C.5/4


D.-2

i think C

Answer 1

ill meadal

Answer 2

The slope formula = \[y2-y1/x2-x1\] In order to find the slope of these points, we must use this formula.

Answer 3

k

Answer 4

So your y1 and y2 are the y values. What are your y values?

Answer 5

4 and 1

Answer 6

Close, your y values are -5 and 1.
Your x values are 1 and 4. See:

(x, y)
(1, -5)
(4, 1)

Answer 7

oh

Answer 8

Your y2 value is the second y value. So if your y values are -5 and 1 which one is the second y value?

Answer 9

4 and 1?

Answer 10

No, your only y values are -5 and 1. So these are your only options. Which one is the second one? It's 1.

Answer 11

ok

Answer 12

So if our formula is y2−y1/x2−x1

We plug in our values:

1-(-5)/4-1

Answer 13

What is 1-(-5) and 4-1?

Answer 14

\[1-(-5)=1+5\]

Answer 15

Good. So 6 is the y and then the x is 4-1 which is 3. So we have 6/3.

What is 6 divided by 3?

Answer 16

2

Answer 17

That's your answer.

Answer 18

\[6\div3=2\]

Answer 19

thx

Answer 20

That is your final slope, yes. No problem.
