12/30=0.4 x 100= 40% that finished the race
30-12=18, 18 cars didn't finish the race
18/30=0.6 x 100=60% that didn't finished the race

The slope of this straight line is equal to: A. 2

<h3>What is a slope?</h3>

A slope is also referred to as gradient and it's typically used to describe both the direction, ratio, and steepness of the function of a straight line based on its coordinates or points.

<h3>How to calculate the slope of a line?</h3>

Mathematically, the slope of any straight line can be calculated by using this formula;

Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}

By critically observing the given graph, we can logically deduce the following points:

  • Point (x, y) = (1, 1)
  • Point (x, y) = (-1, -3)

<u>Note:</u> Each interval on this graph represents 1 unit.

Substituting the given points into the formula, we have;

Slope = Δy/Δx

Slope = (-3 - 1)/(-1 - 1)

Slope = -4/-2

Slope = 2
