Step-by-step explanation:

14. Reflection

15. A

16. D

Step-by-step explanation:

A reflection creates a mirror image of the original figure because if you think of a mirror, you think of your or an object's reflection.

For number 15, the image is unclear so I will just tell you how to do it. When it says translate 6 units right, and 3 units up, you would need to move every point to the next line, at the right side 6 times. Then, you move every point to the top 3 times and plot your new points.

Number 16 is also unclear, so as many numbers it takes you to get to the x-axis, that is the amount you will move the point away from the exact point on the x-axis. For instance, it takes point C 1 unit to get to the x-axis, so we will plot it 1 point into the x-axis. At the end of this, you should see the image like the pre-image. So it will look like a mirror.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
