what? Can't plug in a value for x and evaluate? For example,
f(23) = 4*23-2 = 90
direct variation means that y = kx
So, plug in the numbers and find k.
Evaluate the function when x=1. f(x)=4x-2. Write the input and output as a set of ordered pairs, and identify the domain and range of the ordered pair.
Ordered Pair:
Domain:
Range:
2. Write an equation of direct variation that passes through the point (9,1).

Hey becky, i've seen a lot of your answers and i noticed that you are also from connexus, doing the same year as i am. Maybe we could study together? :D I can make a discord server or something ^-^
Where did the 23 come into play?
