Answer:


y = 50x

Explanation:

Let's start off by trying to find the slope/gradient (commonly denoted as
m) of this function


m = (\Delta y)/(\Delta x)

This means we divide the change in y over the change in x

Let's pick, for example, x = 3 (who's corresponding y is 150) and x = 4 (who's corresponding y is 200)


m = (200 - 150)/(4 - 3)\\\\m = 50

Now we have this:


y = 50x+b

Let's plug in a random value of x and y from this function in order to find b. I'll pick x = 2:


100 = 50\cdot 2 + b\\100 = 100 + b\\b = 0

Since b is 0, we don't have to write it on our equation, meaning that our final equation is just


y = 50x

To verify this, let's say we didn't know the value of y when x is equal to 4 and all we had was that equation:


y = 50\cdot 4\\y = 200

Just like it is on the graph :)

Good luck!
