Question

What is the slope of the line passing through the points (–3, 4) and (2, –1)?

Answer 1

The slope of the line through points (x1,y1) and (x2,y2) is given by :
\(\huge m=\frac{y_1-y_2}{x_1-x_2}\)
now,just put the values and find m.

Answer 2

that makes no sense to me

Answer 3

A. 1
B. -1
C. 3/5
D. -3/5

Answer 4

slope(m) = (y2 - y1) / (x2 - x1)
(-3,4) x1 = -3 and y1 = 4
(2,-1) x2 = 2 and y2 = -1

now sub those numbers into the formula

Answer 5

you still need help ?

Answer 6

yes

Answer 7

i dont understand

Answer 8

slope = (y2 - y1) / (x2 - x1)
your set of points are set up like this (x,y)

make one set be set 1 and the other set be set 2..
set 1 (-3,4) ....here x1 = -3 and y1 = 4
set 2 (2,-1)...here x2 = 2 and y2 = -1

do you understand this ?

Answer 9

-10/6

Answer 10

slope = (y2 - y1) / (x2 - x1)
x1 = -3
x2 = 2
y1 = 4
y2 = -1
we will sub now...
slope = (-1-4) / (2 - (-3)
slope = -5/(2 + 3)
slope = -5/5 = -1

do you see how I did this ?

Answer 11

yes now i under stand thank you so much

Answer 12

can you help me with more?

Answer 13

good to hear :) It is not really that hard as long as you label your points correctly

Answer 14

I can help you with more

Answer 15

What is the slope of the line passing through the points (2, 5) and (0, –4)?

Answer 16

A. 9/2
B. 2/9
C.-9/2
D. -2/9

Answer 17

set it up the same way...
(2,5) x1 = 2 and y1 = 5
(0,-4) x2 = 0 and y2 = -4

now just sub your points into the slope formula : slope = (y2 - y1) / (x2 - x1)

lets see what you can do...I will check your answer. Try to set it up.

Answer 18

you going to try ?

Answer 19

ya

Answer 20

i got 3/-4

Answer 21

hold on...give me a sec to check

Answer 22

slope = (-4-5) / (0 - 2)
slope = -9/-2 = 9/2

show me how you are getting your answers because you are doing something wrong

Answer 23

i had my numbers wrong i did (5-2) / (-4-0)

Answer 24

What is the slope of the line whose equation is 4x – 6y = 12?

Answer 25

you have to be sure and label your numbers correctly and put them in the right spot.

Answer 27

if you are given an equation and you want to find the slope, put the equation in y = mx + b form, and m is your slope. Can you put the equation in y = mx + b form ?

Answer 28

no?

Answer 29

A. -4
B. -2/3
C. 2/3
D.6

Answer 30

4x - 6y = 12 -- we want the y term by itself, so we must subtract 4x from both sides.
4x - 4x - 6y = -4x + 12 -- the 4x's cancel on the left side
-6y = -4x + 12 -- now we need y by itself, so we will divide by -6
-6y/-6 = -4/-6x + 12/-6
y = 4/6x - 12/6 -- reduce
y = 2/3x - 2
the slope is in the m position, so your slope is 2/3

Answer 31

thank you so much i got a 100% on my test thank you thank you!!!! :)

Answer 32

your very welcome...keep practicing these problems and you will ace how to do them, and soon you will be teaching others how to do them.
