Explain the steps for writing an equation of a line that passes through (4,7) and has a slope of 1/2

Which is the value of this expression when p=(-2) and q=(-1)

The volume of a sphere is increased by 6%. calculate the corresponding percentage increased in it area.

When you dilate a figure with a scale factor of 1/2, what will the dilated figure look like?                                                                                           a: the dilated figure will have side lengths that are half the length of the original side lengths.                                                                          b: the angles in the dilated figure will be half the measure of the original figure.                                                                                c: the dilated figure will have side lengths twice the length of the original.
