All you have to do for this is follow the midpoint formula.
Let me know if the picture is unclear and I'll type it out for you.
X=105°
Y=105°
Z=105°
let the angle below 75° which is the 4th Street be A
75°+A=180°[being adjacent angle]
A=105°
X=A[Verticall opposite angle]
Z=A[Corresponding angle]
Y=X[alternate angle]
You have to combine like numbers
y-4x-1(1-6x)+3y+x
4y -4x-(1-6x)+x
4y - 4x - 1 + 6x + x
4y + 3x - 1
Answer:
1) convert these words into 2 equations:
x+y=6
y=x+4
1) for the first equation graph by intercepts:
x intercept: x+0=6
x=6
y intercept: 0+y=6
y=6
hence put point (0,6) and (6,0) on the graph
2nd equation:
graph by slope intercept: go to (0,4) on the graph. go up one and over one to the right. You should end up at (1,5)
so graph (0,4) and (1,5)
hope this helps
