Answer:
If I'm correct the slop appears to be 3x or (3/1)x
Step-by-step explanation:
First of all we need to remember rise/run (y/x) and that we begin calculating the slope by starting at the first point we are given on the graph
This linear equation goes up or "rises" up 3 on the y-axis till it meets a specific x-value giving us our rise of 3. Next we check on our "run" over the x-axis, which we find to be 1. The rise will represent our numerator and the run will represent our denominator. Thus we have 3/1 or a slope of 3.
You can also calculate this by picking the first given point on our line and finding its x and y coordinates on the plane. Then we can locate another point on the line and find its x and y coordinates as well. We take these two points' coordinates and divide using the point-slope formula. (x1,y1)/(x2,y2). I can't clearly see the points on your graph otherwise I'd tell you how to complete the point-slope formula in this example. However, we can eyeball it by using the first method (which isn't always accurate so I recommend using the point-slope formula when you can).
5^(x+7)=(1/625)^(2x-13)
We move all terms to the left:
5^(x+7)-((1/625)^(2x-13))=0
Domain of the equation: 625)^(2x-13))!=0
x∈R
We add all the numbers together, and all the variables
5^(x+7)-((+1/625)^(2x-13))=0
We multiply all the terms by the denominator
(5^(x+7))*625)^(2x+1-13))-((=0
We add all the numbers together, and all the variables
(5^(x+7))*625)^(2x-12))-((=0
We add all the numbers together, and all the variables
(5^(x+7))*625)^(2x=0
not sure if this is right :/

I think it would be a one to one function.
I would probably have to go with 62.5
