Answer 1

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

What is a slope?

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.

How to calculate the slope of a line?

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)

Note: 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
