To find the slope of a line, you can use the formula:

slope = (change in y) / (change in x)

1. Given the points (-2, -3) and (1, 1), we can calculate the change in y and change in x as follows:

change in y = 1 - (-3) = 4
change in x = 1 - (-2) = 3

Therefore, the slope of the line passing through these points is:

slope = (4) / (3) = 4/3

So, the correct answer is the fraction four thirds (4/3).

2. For the equation -4y = 8x, the constant of variation can be found by rearranging the equation to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. In this case, the equation can be rearranged as:

y = -2x

Since the slope of this equation is -2, the constant of variation is -2.

So, the correct answer is -2.

3. If y varies directly with x, it means that the ratio of y to x remains constant. This can be expressed as an equation:

y = kx

where k is the constant of variation.

Given that y = 24 when x = 8, we can substitute these values into the equation to solve for k:

24 = k * 8

k = 24/8 = 3

Now, we can find the value of y when x = 10 by substituting k = 3 and x = 10 into the equation:

y = 3 * 10 = 30

So, the value of y when x = 10 is 30.

Therefore, the correct answer is 30.
