a straight line is 180° so:
x+2/3x=180
multiply everything with 3 so that you'll looser the denominator:
3x+2x=540
5x=540
x=540:5
x=108
(2/3x= 72)
Exact Form:
x
=
7
8
x
=

Decimal Form:
x
=
0.875

Answer:
Blue Line: y = 4x - 1
Green Line: y = -x + 6
Red Line: y = -x
Step-by-step explanation:
Looking at the equation y = mx + b
- The first giveaway is that the green line is the highest y-intercept (b- value). So we can say it's y = -x + 6
- Second giveaway is that the blue line has the lowest y-intercept (again the b- value). So we can say it's y = 4x - 1
- Third giveaway is that the red line has the same x-intercept AND y-intercept which is y = -x. Both intercepts are (0, 0).
Lastly, the rest of the statements are true in correspondence of the last 3 statements.
