Question

The graph of a line passes through the two points (-2, 1) and (2, 1).

Part 1

Graph the line through the two points (-2, 1) and (2, 1). Based on the graph of the line only, determine the slope and y-intercept of the line.

Part 2

Write the equation, in slope-intercept form, of the line that passes through the points (-2, 1) and (2, 1).

Complete your work in the space provided or upload a file that can display math symbols if your work requires it. Be sure to include all of the answers for Parts 1 and 2.

Answer 1

Do you know how to graph it the old school way by plugging in points into the equation and then graphing it?

If you don't, it's probably a good idea to learn that. Otherwise if you do know, we can just go ahead and use a graphing calculator to get us started (:

Answer 2

i dont im sorry

Answer 3

No worries!

Have you seen an xy-coordinate before?

Answer 4

yes

Answer 5

I'm sorry I misread the question. I thought they gave us an equation.

We first have to come up with the equation.

Do you know how to find the slope between two points?

Answer 6

nope
sry

Answer 7

Or if you graph the two points you can see what the line looks like

Answer 8

That black line is the line that goes between (-2, 1) and (2, 1)

What is the slope of the horizontal line?
What is the y-intercept?

Answer 9

idk this is y i asked for help

Answer 10

They really don't teach anything in schools anymore :(

Answer 11

ikr

Answer 12

So the slope is just the rate of change. It's the ratio of how much the y-value changes by how much the x-value changes.

Answer 13

You should know this

Answer 14

So look at our line again, what would the slope be?

Answer 15

0

Answer 16

Exactly!

Answer 17

yayy im smart thx to u

Answer 18

i'm trying to help visualize it

Answer 19

Now the y-intercept is when the line crosses the y-axis

What is the y-value when the line crosses the y-axis?

I think quadrants is a bit out of scope, wouldn't you say?

Answer 22

ummmm yea

Answer 23

thx both of u hmu when u can

Answer 24

welp, im no help-

Answer 25

The above drawing is just an example. So look back at our line

the y-intercept is when the line crosses the y-axis which happens x=0

What is the y-value where the line crosses the y-axis?

You made a mistake when plotting the points :)

Answer 27

im so sry but i gtg thx both of u😉

Answer 28

No problem! If you want me to check your answer whenever you come back, I can do that!
