We want to find the slope of the graph. The formula for calculating slope is expressed as
slope = (y2 - y1)/(x2 - x1)
where
y1 and y2 are the y coordinates of initial and final points on the line.
x1 and x2 are the x coordinates of initial and final points on the line.
Locating initial and final points on the line, we have
when x1 = 1, y1 = 2000
when x2 = 2, y2 = 3500
By substituting these values into the formula, we have
slope = (3500 - 2000)/(2 - 1) = 1500/1
Slope = 1500
