The equation represented by the graph is:
y = 50x + 25
How to find the linear equation?
The general linear equation in slope-intercept form is:
y = mx + b
Where m is the slope and b is the y-intercept.
Here we can see that the y-intercept is y = 25, then we can write:
y = mx + 25
We also can see that we have the point (2, 125) in the graph, replacing these values in the equation above we will get:
125 = m*2 + 25
125 - 25 = 2m
100 = 2m
100/2 = m
50 = m
The equation is:
y = 50x + 25
