Briefly explain what the student did wrong.
Slope: 2/3
Points: (1,3) (4,1)
(The graph is showing a line going downwards on a positive x and y, the y reaching 3 and the x reaching 5.)

The student made an error in calculating the slope. The correct slope between the two points (1,3) and (4,1) is -2, not 2/3.
What is the slope in this table?
x - 0, 2, 4
y - -1, -2, -3
x - 0, 2, 4
y - -1, -2, -3
To calculate the slope from this table, we can use the formula:
slope = (change in y) / (change in x)
Given the points (0, -1) and (4, -3), the change in y is -3 - (-1) = -2 and the change in x is 4 - 0 = 4.
Therefore, the slope is -2/4 = -1/2.
slope = (change in y) / (change in x)
Given the points (0, -1) and (4, -3), the change in y is -3 - (-1) = -2 and the change in x is 4 - 0 = 4.
Therefore, the slope is -2/4 = -1/2.
