Write an equation that is parallel to y = 9x and goes through the point (1,5).

y=9x-4

OR

y-5=9(x-1)

(both are correct and equal)

Step-by-step explanation:

Parallel means slope is the same, so the slope of the equation should be 9.

Using point slope form:

Which would be:

in slope intercept form.

A

Step-by-step explanation:

In a function, the x value can only go to one y value

B has x=5 going to y = 13 and y = 17

C had x = -3 with y values of 1 and -1

D has x = -4 going to y = 52 and 16

A each input has only one output value
