Exercise 1 Page 64

Does substituting the point into the equation result in a true statement?

No.

Practice makes perfect

To determine if a point is a solution to an equation, we substitute the point into the equation and simplify. If the resulting statement is true, then the point is a solution to the equation. Let's test the given point.

y=x-2

x= 2, y= 4

4? = 2-2

Subtract term

4≠0 *

Since 4 is not equal to 0, the statement is false. Therefore, the point (2,4) is not a solution to the equation.
