The scales on both axes of the standard (x,y) coordinate plane below (September 2023 - G01)
The scales on both axes of the standard (x,y) coordinate plane below are the same. Of the following values, which one is the best estimate for the slope of the line graphed in the plane?
E. -5
G. - 1/5
H. 1/5
J. 3/5
K. 5
Solution
Correct answer: G. - 1/5.
Observe the direction of the line on the graph. Since the line is trending downward from left to right, it has a negative slope.
Determine the relationship between the rise and the run of the line. The run is greater than the rise, which means the slope is less than 1 in absolute value.
Among the given options, the only negative fraction less than 1 in absolute value is - 1/5
