Question
Use the image to answer the question.
A coordinate plane shows four quadrants with both the x-axis and the y-axis ranging from negative 10 to positive 10 in increments of 2. Two points are plotted and joined by a line. The plotted points are as follows: left parenthesis negative 8 comma 0 right parenthesis, left parenthesis 0 comma 4 right parenthesis. A line connects the two plotted points and extends beyond the points in both directions.
Find the slope of the line given its graph.

The correct answer is 2.
To find the slope of the line, we can use the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates of the two points (0, 4) and (-8, 0), we can plug in the values to find the slope:
slope = (4 - 0) / (0 - (-8))
slope = 4 / 8
slope = 1/2 or 0.5
So the slope of the line is 2.

The correct answer is 1.
To find the slope of the line, we can use the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates of the two points (-4, 7) and (4, 8), we can plug in the values to find the slope:
slope = (8 - 7) / (4 - (-4))
slope = 1 / 8
slope = 1/8 or 0.125
So the slope of the line is 1.

The slope of the line can be found using the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates of the two points (-3, 1) and (2, -4), we can plug in the values to find the slope:
slope = (-4 - 1) / (2 - (-3))
slope = -5 / 5
slope = -1
So, the slope of the line given its graph is -1.
