Exercise 5 Page 417

Substitute the ordered pair into the given equation and simplify.

Yes

In an ordered pair, the first coordinate corresponds to the x- value and second to the y- value. ( 2, 8) ⇕ x = 2, y = 8 We can determine whether (2,8) is a solution by substituting it into the equation and simplifying. Let's substitute 2 for x and 8 for y.

y = 4x

x= 2, y= 8

8 ? = 4 * 2

Multiply

8 = 8 ✓

We got a true statement. This means that the ordered pair (2,8) is a solution of the equation.
