Based on the calculations, the slope of this line is equal to 50.
What is a slope?
The slope of a line refers to the gradient of a line and it can be used to describe both the ratio, direction and steepness of an equation of a straight line.
How to calculate the slope of a line graph?
Since the line passes through two (2) points, the slope of this line would be calculated by using this formula;
[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]
Substituting the given parameters into the formula, we have;
Slope = (100 - 0)/(2 - 0)
Slope = 100/2
Slope = 50.
Based on the graph, we can deduce that the distance for each hour increases by 50 miles since Bill crossed the bridge.
