Option A is correct

35 miles per day

Step-by-step explanation:

Using slope formula:

$\text{Slope (m)} = \frac{y_2-y_1}{x_2-x_1}$ ....[1]

From the given graph:

Here, y represents the distance in miles and x represents the time in days

Consider two points i.e

(2, 70) and (4, 140)

then;

Substitute these in [1] we have;

$m = \frac{140-70}{4-2} = \frac{70}{2} = 35$

Therefore, the rate of change or slope of the given line is, 35 miles per day
