Answer:
Please see the attached images for full solution.
For question 3, the equation could have also been 3x°= 90°. However, I used ∠ sum of △ since I didnt want to assume that ∠ABC is a right angle.
Likewise for Q4, the polygon looks like a trapezium which means that the 2 horizontal lines are parallel and one could conclude that (3x +3)° +(2x +2)°= 180° (int. ∠s). But since it wasn't clearly indicated that they are parallel, I used the sum of interior angles to find x instead.
Answer:
For table :
X------Y
0------6
1------2
Figure show equation of line: y=6-4x
Step-by-step explanation:
Given equation is y=6-4x
To plot the equation of line, we need at least two points.
Take x=0
The respective value of y on line is
y=6-4x
y=6-4(0)
y=6
The required point is A(0,6)
Take x=1
The respective value of y on line is
y=6-4x
y=6-4(1)
y=2
The required point is B(1,2)
For table :
X------Y
0------6
1------2
Figure show equation of line: y=6-4x
