Question

Please help! I don't get any of this! :(


1. What is the slope of in the graph below?


A. -2
B. -1
C. 1
D. 2


2. Find the slope of a line that passes through (-2,-3) and (1,1).

A. 1/3
B. 1
C. 2
D. 4/3

Answer 1

where is the graph

Answer 2

One sec

Answer 3

There

Answer 4

For the first one, the slope is -2, or -2/1.
As you can see, the rise is -2, and the run is 1. Rise always goes over the run.
If the slope has the number 1 underneath the rise, you can simply just say that the slope is the rise, like the -2.
So, the answer is B. -2.
Does that clear things up?

Answer 5

Yes thank you :)

Answer 6

You're welcome! (:

Answer 7

Slope = \(\frac{rise}{run}\)

The rise is already given, which is -2, and the run is 1, so we replace -2 with tise and 1 with the run \(\frac{-2}{1}\) = -2

Answer 8

I am lagging so much

Answer 9

3-1 / 0 - 1 = -2 ( the first question)
y2-y1/x2-x1

Answer 10

-3 - 1 / -2 - 1 ) -4 / -3 = 4/3 so the answer is D

Answer 11

so 1 is D?

Answer 12

For the second one, use the slope formula.
\[\frac{ y2-y1 }{ x2 -x1}\]
Plug in the two points.
(-2, -3) (1, 1)
1 is y2, and -3 is y1.
1 is x2, and -2 is x1.
\[\frac{ 1 - (-3) }{ 1 - (-2) } = \frac{ 1 + 3 }{ 1 + 2 } = \frac{ 4 }{ 3 }\]
So, the answer is D. 4/3.
It's really simple when you memorize the formula, huh? (:

Answer 13

Can you help me with a few more?

Answer 14

Summary: (I said B. -2 for the first one, but -2 is A, not B haha, sorry.) So, the first one is A. -2, and the second one is D. 4/3

Answer 15

I'll try. Close this first and ask the questions in a new post. (:

Answer 16

Okay will do
