Can anyone help me please ??

Choice A is correct

Explanation:

Each time x goes up by 1, y goes up by 100 (eg: from 50 to 150, so 150-50 = 100).

We then say,

slope = rise/run

slope = (change in y)/(change in x)

slope = (100)/(1)

slope = 100

The rate of change is $100 per deposit

We could also use the slope formula. Pick any two points on the diagonal line. Let's say we picked (1,150) and (3,350)

m = (y2-y1)/(x2-x1)

m = (350-150)/(3-1)

m = (200)/(2)

m = 100

Or we could pick (0,50) and (1,150) as our two points

m = (y2-y1)/(x2-x1)

m = (150-50)/(1-0)

m = (100)/(1)

m = 100

Either way, the slope is m = 100.
