Answer:
Reflection
Step-by-step explanation:
Figure A' is the reflection of A as it is reflected from A'
Answer:
C.
Step-by-step explanation:
3(2x + 1)=6x + 3
3*2x=6x, 3*1 = 3
so therefore 3(2x+1)=6x + 3
To construct the equations for these lines, we are going to use the point-slope formula, which is:
![(y - y_1) = m(x - x_1)](https://tex.z-dn.net/?f=%28y%20-%20y_1%29%20%3D%20m%28x%20-%20x_1%29)
is the slope of the line
is a point on the line
1)
In this case, our point is (2, -1) and our line has a slope of 5. (Remember that the line is parallel, meaning that it has the same slope as the given line. Since the line is in the y = mx + b format, we could easily pick out the slope m as being 5.)
Thus, we can "plug in" what we know into our formula to find the equation of our line:
![(y + 1) = 5(x - 2)](https://tex.z-dn.net/?f=%28y%20%2B%201%29%20%3D%205%28x%20-%202%29)
![(y + 1) = 5x - 10](https://tex.z-dn.net/?f=%28y%20%2B%201%29%20%3D%205x%20-%2010)
![y = 5x - 11](https://tex.z-dn.net/?f=y%20%3D%205x%20-%2011)
2)
We are going to do the same thing, except our point is now (0, -5) and our slope is now 9.
![(y + 5) = 9(x - 0)](https://tex.z-dn.net/?f=%28y%20%2B%205%29%20%3D%209%28x%20-%200%29)
![y = 9x - 5](https://tex.z-dn.net/?f=y%20%3D%209x%20-%205)
Our equations are:
1) y = 5x - 11
2) y = 9x - 5
The supplement of 89° is the angle that when added to 89° forms a straight angle (180° ).
