Answer:

Step-by-step explanation:

We need to use two points on the line: (0,50) and (2,100).

Then, we find the slope with the formula

$m=\frac{y_{2}-y_{1} }{x_{2} -x_{1} }\\ m=\frac{100-50}{2-0}=\frac{50}{2}=25$

Then, we use the point-slope formula to find the equation

$y-y_{1} =m(x-x_{1} )\\y-50=25(x-0)\\y=25x+50$

Therefore, the right answer is B.
