Question

Determine whether the ordered pair (2, 13) is a solution of the equation y = 4x + 5.

Explain what your answer (it being a solution, or not) tells you. In other words, what do you know about this point?

Answer 1

To find whether or not the set is a solution, we substitute the numbers in with the x and y values.

`x=2`

`y=13`
Which gives us...

`13=4(2)+5`
Now we ask ourselves, does this satisfy the equation?

`13=13`
Which it does. This tells us that the point (2,13) is on the line
`y=4x+5`
