Point a is at (-3,-5) and point b is at (1,-9) what is the midpoint of the line segment ab

The midpoint is (-1,-7)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates together and divide by 2

(-3+1)/2 = -2/2 =-1

To find the y coordinate of the midpoint, add the y coordinates together and divide by 2

(-5+-9)/2 = -14/2 =-7

The midpoint is (-1,-7)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
