Question

what is the slope of the line.

Answer 1

@Ashes.boom

Answer 2

hello

Answer 3

Hey! I found it sorry that took so long

Answer 4

Do you remmeber the equation to find the slope of a line?

Answer 5

yes

Answer 6

mx +b

Answer 7

that is slope intercept form which is what we need but to find the slope you use a different formula. You use y2 - y1 / x2 - x1

Answer 8

ok

Answer 9

im confused what the answer

Answer 10

so just pick two points on the line that is graphed and tell me what they are okay

Answer 11

is it 3 and 1

Answer 12

umm slope is normally going to be a fraction like a number over a number so did you mean 3/1

Answer 13

yup

Answer 14

so if you use the points on the line that they gave you which were (1, 4) (2, 1) can you see where those are?

Answer 15

yup

Answer 16

use them in your equation to find the slope. The point closest to the left is the first point so the x and y values for that one will be x1 and y1 the other point will be x2 and y2

Answer 17

so 1, 4 is the 1 point okay and the other is the second

then when you put them into the equation you have

1 - 4 / 2 - 1

Answer 18

right?

Answer 19

no

Answer 20

-3,3 1/3,-1/3 are the options

Answer 21

yea we havent finished yet though if you simplify what i wrote you get -3/1 which is -3. okay?

Answer 22

oh srry

Answer 23

your right i just figured that out

Answer 24

its okay haha it makes sense tho right?

Answer 25

Take two points on the line where you can easily find their coordinates (the two red dots would be excellent choices here). Call those points \((x_1,y_1)\) and \((x_2,y_2)\). The slope of the line (\(m\)) is given by

\[m = \frac{y_2-y_1}{x_2-x_1}\]

Answer 26

If you move from left to right, the slope is just the change of the height divided by the distance you moved to the right. If the line goes up as you move the right, the slope is positive, if it goes down the slope is negative. A perfectly horizontal line (parallel to x-axis) has a slope of 0, and a perfectly vertical line (parallel to y-axis) has an infinite or undefined slope.
