Solutions to Equations

Multiple Select

How do we determine if an ordered pair is a solution to an equation?

• Graph it and see if the point is on the line.

• Plug the ordered pair into the equation.

• Find the slope of the ordered pair.

• Graph it and find rise over run.

If you don't have a graph, plug the ordered pair into the equation.

• If both sides are equal, then the ordered pair is a solution.

• If both sides are not equal, then the ordered pair is a not solution.

Multiple Choice

Is (2, 4) a solution to the equation

 $y=5x-6$  ?

• Yes

• No

Is (2, 4) a solution to the equation y=5x−6?

• 4 = 5(2) - 6

• 4 = 10 - 6

• 4 = 4

• So, the answer is yes!

Multiple Choice

Is (0, 4) a solution to the equation

 $y=-2x+3$  ?

• Yes

• No

Is (0, 4) a solution to the equation y=-2x+3?

• 4 = -2(0) + 3

• 4 = 0 + 3

• 4 = 3

• So, the answer is no!
