Find x-intercept and y-intercept then you can draw the graph.
For example, the first question.
To find the y-intercept, x = 0
So substitute x = 0 in the equation.
[Note]: You don't need to find the y-intercept, because from, 
a is slope and b is y-intercept, you know b then you know y-intercept. For example b = 2 then y-intercept is at 2.
To find the x-intercept, y = 0
Therefore, y-intercept = 2 and x-intercept = 2/3
(Try do another problems, just do the same. When you want to find the y-intercept, just look at the value of b or substitute x = 0 and When you want to find the x-intercept, just substitute y = 0 then solve for x.)
Answer:
1/20
Step-by-step explanation:
Question 11
x+x+1/2x+1/2x=360
x+x+2/2x+=360
x+x+x=360
3x=360
x=120
Then substitute 120 in the place of x
x1=120
x2=120
1/2(120)=60
1/2(120)=60
To check your answer you can add 60+60+120+120 the should be equal to 360
Question 12
x+x+(x-45)+(x-45)+(x-45)=540
x+x+x-45+x-45+x-45=540
5x-135=540
5x=540+135
5x=675
x=675/5
x=135
Then substitute 135 in the place of x
x1=135
x2=135
135-45=90
135-45=90
135-45=90
To check your answer you can add 135+135+90+90-90 the should be equal to 540

Answer:
30 degrees
Step-by-step explanation:
90 + 60 + x = 180
150 + x = 180
-150 -150
x = 30

Step-by-step explanation:
1) If
