MULTIPLE CHOICE QUESTION

Mugdha and Dhruvi are on a treasure hunt and need to find the slope of the path that leads them from point A (5, 8) to point B (−4, 6). Can you help them calculate the slope of the line passing through these points?
The slope of the line passing through the points (5, 8) and (−4, 6) is calculated using the formula: slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) = (5, 8) and (x2, y2) = (−4, 6). Thus, slope = (6 - 8) / (−4 - 5) = -2 / -9 = 2/9.
The slope of the line passing through the points (5, 8) and (−4, 6) is calculated using the formula: slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) = (5, 8) and (x2, y2) = (−4, 6). Thus, slope = (8 - 6) / (5 - (-4)) = 2 / 9.
The slope of the line passing through the points (5, 8) and (−4, 6) is calculated using the formula: slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) = (5, 8) and (x2, y2) = (−4, 6). Thus, slope = (6 - 8) / (5 - (-4)) = -2 / 9.
The slope of the line passing through the points (5, 8) and (−4, 6) is calculated using the formula: slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) = (5, 8) and (x2, y2) = (−4, 6). Thus, slope = (8 - 6) / (-4 - 5) = 2 / -9.
Answer explanation
The correct slope is calculated as (y2 - y1) / (x2 - x1). Using (5, 8) and (−4, 6), we find slope = (6 - 8) / (−4 - 5) = -2 / -9 = 2/9, matching the first answer choice.

Aahana and Anshika are on a treasure hunt! They need to find the slope of the path that leads from the mysterious point (9, 4) to the hidden treasure at (5, −3). Can you help them calculate the slope of their adventurous journey?
The slope of the line passing through the points (9, 4) and (5, −3) is calculated using the formula: slope = (y2 - y1) / (x2 - x1). Here, (x1, y1) = (9, 4) and (x2, y2) = (5, -3). Therefore, slope = (-3 - 4) / (5 - 9) = -7 / -4 = 7/4.
The slope of the line passing through the points (9, 4) and (5, −3) is 4/7.
The slope of the line passing through the points (9, 4) and (5, −3) is -7/4.
The slope of the line passing through the points (9, 4) and (5, −3) is 0.
Answer explanation
To find the slope between (9, 4) and (5, -3), use slope = (y2 - y1) / (x2 - x1). Here, slope = (-3 - 4) / (5 - 9) = -7 / -4 = 7/4. Thus, the correct answer is 7/4.

Milana and Jovany are on a treasure hunt! They start at the point (0, 5) and move to the point (5, 5) on their map. Can you help them find the slope of the path they took?
0
1
2
undefined
Answer explanation
The slope of a line is calculated as (y2 - y1) / (x2 - x1). For points (0, 5) and (5, 5), the slope is (5 - 5) / (5 - 0) = 0 / 5 = 0. Thus, the correct answer is 0.

In 2005, Aryaa and Mohammed were part of the 12,000 students at Beacon High. By 2010, Anshika joined them, and the student count rose to 12,250. Can you calculate the magical rate of change in the number of students over these years?
250/yr
50/yr
42/yr
200/yr
Answer explanation
To find the rate of change, subtract the initial number of students (12,000) from the final number (12,250) to get 250. Then, divide by the number of years (5). Thus, 250/5 = 50 students per year.

Imagine Jude and Aahana are climbing a mountain, and they want to calculate the slope of their path. Why can't they use the Slope Formula if their path is a vertical line?
Because the slope is undefined for vertical lines.
Because vertical lines have a slope of zero.
Because vertical lines have a positive slope.
Because vertical lines have a negative slope.
Answer explanation
The correct choice is that the slope is undefined for vertical lines. This is because vertical lines do not have a change in x-coordinates, leading to division by zero when calculating slope.
