Question

Is (8,8) a solution to the equation y=x?​

Answer 1

yes

Explanation:

y=x is just a linear function and the slope is 1 to 1.

so the y-intercept is 0 and the the line goes (1,1),(2,2),(3,3),(4,4).....etc so as x increases by 1, y increases by 1 and if it

makes it easier look at this:

y=1x+0

now look at this:

y=x

aren't they the same?

Hope that helps.

Answer 2

Yes

Explanation:

(8,8) is a solution is y=x.

If we substitute the point into the equation, the equation is true.

(8,8) is in (x,y) format

Substitute:

y=x
