A line segment is drawn from (3, 2) to (3, 9) on a coordinate grid.

Which answer explains one way that the length of this line segment can be determined?

A. Add 2 + 3.

B. Add 2 + 9.

C. Subtract 9 – 2.

D. Subtract 3 – 2.

C

Step-by-step explanation:

Only C (subtract 2 from 9) could be true.  This subtraction produces a measure of the vertical distance between the two points.  (3, 9) is 7 units further above the x-axis than is (3, 2).

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
