Question

i need some help

Answer 1

Point-Slope Form
\[y - y_{1} = m(x - x_{1})\]

Answer 2

m = slope = 1.8
x1 = the x point = -4.5
y1 = the y point = 1.4

Answer 3

@princeevee Does that help? And if not, let me know what you don't understand.

Answer 4

@Shadow

Answer 5

Did you get the first question?

Answer 6

\[m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\]
Where m = the slope

Answer 7

In order to solve for the slope, the easy way, when it's possible, is to just count the boxes. You simply need the rise and run between two points (how much it rises by, vertical, and how much it runs by, horizontal).

Answer 8

So,
\[m = slope = \frac{ Rise }{ Run }\]
Between those two points, find how much the line rose by, and how much the line went by.

In other words, find the difference in elevation between the two points (along the y axis), then find the difference between in distance between the two points (along the x axis).

Answer 9

i got -2

Answer 10

What was your calculation?

Answer 11

When a line is going up like this, it's not supposed to be negative.

Answer 12

oh, i divided it by -2 - 2, not 2-(-2)

Answer 13

where i did the negative one first

Answer 14

Ah, so you are using the slope formula
\[m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} }\]

Answer 15

How are you doing with the problem?

Answer 16

shouldnt it be something with 1/2? both of xy1 and xy2 are equally the same

Answer 17

They have the same number but not the same sign.

Answer 18

@Vocaloid

Answer 19

close but be careful about signs

(5-4)/(0-3) gives -1/3 not 1/3

Answer 20

Good

Answer 21

Nice, you are getting this down

Answer 22

The outlier between 10-12 on the x axis and under 2 on the y axis is very obvious, but you don't see any clusters?

Answer 23

i think i see them now

Answer 24

Okay good. I have to head to class so good luck with the rest.
