The slope of the proportional relation is 50.
How to find the slope of the proportional relation?
A general proportional relation can be written as:
y = k*x
Where k is the slope.
To find the value of k, we just need to identify one point in the graph, then we can replace the values of the point in the equation, and find the value of x.
We can identify the point (1, 50), then we get:
50 = k*1
50 = k
That is the slope.
