Question

can I get some help how to do this?

Answer 1

What part are you having trouble with?

Answer 2

figuring the y intercept

Answer 3

according to the question i need to know y int then graph

Answer 4

y = mx + b

b is the y-intercept

y = x - 7

what will be the y-intercept?

Be careful, there is a minus sign

Answer 5

y=x-7
plug in 0 for y

Answer 6

i got 0=x-7 but what do i do now?

Answer 7

when finding the y-intercept, you need to plug in x = 0

when finding the x-intercept, you plug in y = 0

Answer 8

i need the y-int isnt it y=0-7?? @TheSmartOne

Answer 9

yes, and what is 0 - 7 = ?

Answer 10

-7

Answer 11

That is your y-intercept

Answer 12

how do i graph?

Answer 13

Here's a graph of it: https://www.desmos.com

Answer 15

You can plot the point (0, -7) and then you can plug in another value into the equation and find the y-value. You then plot the two points and draw a line between it.

Answer 16

hw do i plug in another value?

Answer 17

plug in x = 1

or x = 5

Answer 18

so how would i do that to y=x-7
wouldnt it be 0=1-7? or 0=5-7? right

Answer 19

yes

and then you get:

(1, -6) and (5, -2)

and you have to draw a line through the points

Answer 20

-7 you b is always your y int
