Question

how to find the x and y intercepts of y=x-5

Answer 1

Set x and y equal to 0 separately.
y = x - 5
y = 0 - 5
Solve here and this will be the y-intercept.
y = x - 5
0 = x - 5
Solve here and this will be the x-intercept.

Answer 2

@Calmathlete so the x intercept is ........
the y intercept is -5

Answer 3

The y-intercept is -5.
Solve for x to get the x-intercept.

Answer 4

x is 0?

Answer 5

Nope...
Get x by itself. What would you do to get rid of that -5?

Answer 6

add 5 to both sides?

Answer 7

Yup. If you do that, the -5 will cancel and x will equal...

Answer 8

1?

Answer 9

i don't understand could you explain it please please?

Answer 10

If you take 0 = x - 5 and add 5 to both sides, what do you get?

Answer 11

0?

Answer 12

0 = x - 5
+5 +5

Answer 13

@jim_thompson5910 we got 5 as x and to find y you just substitute x and then simplify?

Answer 14

You are correct in saying that x = 5 is the x-intercept

You can write the x-intercept as (5,0)

Answer 15

I'm not sure what you mean by "to find y you just substitute x and then simplify"

Answer 16

you mean the y-intercept?

Answer 17

yes

Answer 18

To find the y-intercept, you plug in x = 0 and simplify

Answer 19

y=x-5

y=0-5 ... replace x with 0

and simplify

Answer 20

so y is -5?

Answer 21

yes

Answer 22

thankyou so much yu cleared everything up :)

Answer 23

you're welcome

Answer 24

@jim_thompson5910 one more question sorry
how can u graph a ine using those intercepts?
thankyou so much:)

Answer 25

Above you found the x and y intercepts to be (5,0) and (0,-5) agreed?

Answer 26

yes

Answer 27

These are two points that lie on the line. So plot these two points and draw a line through them to graph y = x-5
