You would need to see the rest of the equation to plug in 7 for x. Treat it as y=equation and replace any x with 7.

Answer:
(0, 2), (5, 5)
Step-by-step explanation:
The w-intercept is the constant in the equation, so you know immediately that (x, w) = (0, 2) is one point on your graph.
Since the value of x is being multiplied by 3/5, it is convenient to choose an x-value that is a multiple of 5. When x=5, we have ...
w(5) = (3/5)(5) +2 = 3+2 = 5
So, (x, w) = (5, 5) is another point on your graph.
Answer:
x = 0.447
Step-by-step explanation:
You need to use your graphing calculator for this.
In y=, put 13(0.25)^x in Y1 and put 7 in y2. Using 2nd trace, find the intersections.
The answer I got was x = 0.447.
