Question

Compare and Contrast. Below are two sets of points. Find the slopes between the two points and compare them. Choose the statement that is true about the values of the slopes.

please help

Answer 3

do you know how to find the slopes of the points ?

Answer 4

why did you close the question ? Do you still need help ?

Answer 5

no

Answer 6

ok :) bye for now

Answer 7

oh yes i need help

Answer 8

on this question ?

Answer 9

yes

Answer 10

lets find the slopes using the slope formula : slope(m) = (y2 - y1)/(x2 - x1)

set 1
(0,4) x1 = 0 and y1 = 4
(-2,8) x2 = -2 and y2 = 8

lets sub our info in :
m = (8 - 4) / (-2 - 0)
m = 4/-2
m = -2 <-- slope

you see how I found the slope for set 1 ?

Answer 11

yes but it says The slope of Set #1 is smaller than the slope of Set #2.

The slope of Set #1 is larger than the slope of Set #2.

The slope of Set #1 is the same as the slope of Set #2.

None of the statements above describes slopes of sets shown.

Answer 12

now we need to find the slope of set 2 and compare them.

m = (y2 - y1) / (x2 - x1)
(3,7) x1 = 3 and y1 = 7
(-1,-5) x2 = -1 and y2 = -5

m = (-5 - 7) / (-1 - 3)
m = -12/-4
m = 3

slope for set 1 is -2 and slope for set 2 is 3
so what do you think the answer is ?

Answer 13

i think its a

Answer 14

you are correct :)

Answer 15

good job :)

Answer 16

do you need anymore help ?

Answer 17

thank u and yes i do

Answer 18

what do you need help with ?

Answer 19

Which of the following is not a step used when graphing the equation x + 3y = 3 using the
x- and y- intercepts method?

Plot the y-intercept (0, 1).

Plot the intercept (3, 0).

Count down 1 and right 3 from the y-intercept.

Draw a line through the two points

Answer 20

i think its b

Answer 21

i mean c

Answer 22

it is C

Answer 23

i got What is the slope of the line 2x - 5y = -10?

negative five halves

five halves

two fifths

negative two fifths

none of the above

Answer 24

nd i think its none of the above

Answer 25

2x - 5y = 10
-5y = -2x + 10 (multiply by -1 to make y positive)
5y = 2x - 10 (now divide by 5)
y = 2/5x - 2
y = mx + b and m is your slope, therefore your slope is 2/5

Answer 26

wait...I wrote the problem down wrong...hold on

Answer 27

ok

Answer 28

2x - 5y = -10
-5y = -2x - 10
5y = 2x + 10
y = 2/5x + 2

it didn't matter, the slope is still 2/5

Answer 29

Explain how to graph 2x + y = 14 using the x- and y-intercepts method. Be sure to use complete sentences and use the x- and y-intercepts method only.

Answer 30

to find the x intercept, sub in 0 for y.
2x + y = 14
2x + 0 = 14
2x = 14
x = 7 <-- x intercept = (7,0)

to find the y intercept, sub in 0 for x
2x + y = 14
2(0) + y = 14
y = 14 <-- y intercept = (14,0)

so you have a point on the x axis at 7 and a point on the y axis at 14.
Now just draw a line connecting the two points.

Answer 31

thank yu so much

Answer 32

no problem :)

Answer 33

;] your the best

Answer 34

I don't know about that...but thank u anyways :)

Answer 35

lol its tru
