Question 4

Find the midpoint of the segment joining the points (-9, 10) and (5, 0)

Accepted Answer

The midpoint of a segment with endpoints (x1, y1) and (x2, y2) is given by ((x1 + x2)/2, (y1 + y2)/2). For the points (-9, 10) and (5, 0), the midpoint is ((-9 + 5)/2, (10 + 0)/2) = (-2, 5).

Question 5

Find the midpoint of the segment joining the points (-5, -3) and (-6, -6).

Accepted Answer

The midpoint of a segment with endpoints (x1, y1) and (x2, y2) is given by the formula ((x1 + x2)/2, (y1 + y2)/2). Applying this to the given points (-5, -3) and (-6, -6) gives ((-5 - 6)/2, (-3 - 6)/2) = (-11/2, -9/2) = (-5.5, -4.5).

Question 10

Which of the following applies to the graph y = 8x³?

Accepted Answer

The equation y = 8x represents a straight line through the origin with a slope of 8. This line is symmetric with respect to the origin because reflecting it across the origin (by changing the sign of both x and y) does not change the equation.

Question 13

Use algebraic tests to determine whether the graph of the equation y = | x | + 11 is symmetric with respect to the x-axis, y-axis, or origin.

Accepted Answer

The graph of y = |x| + 11 is symmetric with respect to the y-axis because replacing x with -x does not change the equation (y = |-x| + 11 = |x| + 11). It is not symmetric with respect to the x-axis or the origin because replacing y with -y does not yield an equivalent equation.

Question 14
