Answer:
This is a reflection about the x-axis.
Step-by-step explanation:
A reflection about the x-axis has the rule
[x,y]-> [x,-y].
Therefore
M[x,y] = [x,-y}
Let M=
|a b|
|c d|
Then the matrix multiplication gives
ax+by=x.............(1)
cx+dy=-y............(2)
Solving the previous equations (1) and (2) gives
a=1, b=0
c=0, d=-1
giving M as
|1 0|
|0 -1|
Answer:
135°
Step-by-step explanation:
a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.
180 - 45 = 135, therefore the measure of ZB = 135°.

Answer:
y-intercept = (0, -2)
x-intercept = (2, 0)
Step-by-step explanation:
The y-intercept is the value of y when x = 0. Therefore, Given the linear equation, y = x - 2:
Let x = 0:
y = 0 - 2
y = -2.
Therefore, the y-intercept of the linear equation, y = x - 2 is (0, -2).
The x-intercept is the value of x when y = 0.
Therefore, let y = 0:
y = x - 2
0 = x - 2
Isolate x by adding 2 to both sides of the equation:
0 + 2 = x - 2 + 2
2 = x
Therefore, the x-intercept is (2, 0).
