Convert the equation into slope-intercept form:

y - 5x = 10

• y = 2x + 5

• y = 15x

• y = 5x + 10

• y = 5x + 5

Is the relation a function? Why or why not?

• Yes, because the x-value 11 has two y-values pair with it.

• Yes, because each x-value has only one y-value paired with it.

• No, because the x-value 11 has two y-values pair with it.

• No, because each x-value has only one y-value paired with it.
