Does the point (7, 7) satisfy the equation y = x?

Answer 1

Yes, since if you plug into the equation for x = 7 and y = 7, you end up with 7 = 7

Answer 2

As Patrick said, yes.

Some additional explanation: when you are given a point - such as (7, 7), you are being given the x and y coordinates of the point - (x, y).

In this problem, you're being asked if the point (7, 7) satisfies the relationship x = y. Indeed, x = 7 and y also equals 7, so x = 7.

To check your understanding, try the following problems:

Does the point (3, 2) satisfy the relationship y = x + 1?

Does the point (3, 2) satisfy the relationship y = x - 1?

Answer 3

Yes...
