Question

To graph the equation y= -1/2x - 3 using the slope and y-intercept, you would have to do which of the following?

Answer 1

Is there a multiple choice to choose from?

Answer 2

Graph the y-intercept, 3. From that point, move down 1 and to the right 2 to plot another point. Then draw a line that passes through both points.

Graph the y-intercept, -3. From that point, move up 1 and to the right 2 to plot another point. Then draw a line that passes through both points.

Answer 3

@Senkai

Answer 4

from the y intercept, which is -3, you come down 1 and go to the right 2, then down 1 and to the right 2. Because the slope (rise/run) is -1/2.

Answer 5

yep so awnser choice C?

Answer 6

correct

Answer 7

i got anthor one @kelliegirl33

Answer 8

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

Answer 9

what are the points ?

Answer 10

set #1 (4,4) and (2,6) and set # 2 (2,4) and (4,2) @kelliegirl33

Answer 11

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

are you familiar with the slope formula ?

Answer 13

yep

Answer 14

so lets find the slopes....
set 1 :
(4,4) x1 = 4, and y1 = 4
(2,6) x2 = 2 and y2 = 6

slope(m) = (y2 - y1)/(x2 - x1)
m = (6 - 4) / (2 - 4)
m = 2/-2
m = -1 (slope of set 1)

set 2 :
(2,4) x1 = 2 and y1 = 4
(4,2) x2 = 4 and y2 = 2

m = (2 - 4) / (4 - 2)
m = -2/2
m = -1 (slope of set 2)

so what do you think the answer is ?

Answer 15

any questions ?

Answer 16

the awnser is C?

Answer 17

yes it is

Answer 18

thanks!!!

Answer 19

glad to help :)

Answer 20

can you help me with one more?

Answer 21

possibly....whatcha got

Answer 22

Using complete sentences, explain how to graph y = negative one fourthx + 8 using the slope-intercept method.

Answer 23

y = -1/4x + 8

In this form, y = mx + b, the slope is m and the y intercept is b.

Therefore, the slope is -1/4 and the y intercept is 8

Start at the y intercept and plot your point on 8.
From that point, come down 1 and to the right 4, then down 1 and to the right 4.
Because the slope is -1/4 (rise/run), since the 1 is negative, you come down 1, and since the 4 is positive, you go to the right 4.

Answer 24

omg thanks so muchh!!!!:)
