Hey!
------------------------------------------------
We can eliminate the bottom two answers because its a full boundary line which is used when the inequality has ≤ or ≥. Now we have to figure out which top one to use. To see which one is correct we can use the point (0, 0) to see if the point should be shaded or not.
y > 1 - 3x
0 > 1 - 3(0)
0 > 1 - 0
0 > 1
This is false when we use (0, 0). So now we know that the point (0, 0) should NOT be shaded.

Hence, the answer is

Hope This Helped! Good Luck!

Step-by-step explanation:
The question has unclear information.
So, I'll answer from scratch
Given
ABC = Right angled triangle
DB bisects ABC
Required
Prove that CBD = 45
From the question, we have that:
ABC is right angled at B
So, when DB bisects ABC, it means that DB divides ABC into two equal angles.
i.e.
and
Substitute CBD for ABD in
Divide both sides by 2
Hence, it is proved that
