Question

use substitution to determine whether the point in on the line y=x+1; A(1,0)

Answer 1

A(1,0) so substitute x = 1 and y = 0

y = x + 1 \[\implies 0 = 1 + 1\]
is this true?

Answer 2

No

Answer 3

then the point is not on the line

Answer 4

But I dont understand how to substitute to figure that out.

Answer 5

A(1,0) is the point

do you know which one is the x-coordinate and which one is the y coordinate?

Answer 6

The X coordinate is 1? & the Y is 0? Sorry, im really bad at math

Answer 7

but that is right

Answer 8

so x coordinate is 1 and y coordinate is 0

your equation is y = x + 1

just substitute 1 into x and 0 into y

that gives you 0 = 1 + 1

got it now?

Answer 9

Yes, I understand. Thank you!
