The equation of the line is y = 50x + 100
How to determine the equation of the line?
From the question, we have the following point on the line
(x, y) = (4, 300)
Also, we have:
Rise = 100
Run =2
So, the slope (m) of the line is
m = Rise/Run
This gives
m = 100/2
Evaluate
m = 50
The equation is then calculated as:
y = m(x - x1) + y1
This gives
y = 50(x - 4) + 300
Expand
y = 50x - 200 + 300
Evaluate
y = 50x + 100
Hence, the equation of the line is y = 50x + 100
