Answer:

Step-by-step explanation:
Notice that ∠7 is the vertical angle to 151°.
Vertical angles have the same measure.
So, ∠7 is <em>also</em> 151°.
Our answer is 151°.
And we're done!
Answer:
y=1/2x+1
Step-by-step explanation:
To change it into slope intercept (y=mx+b) you just replace the inequality with an equality and isolate y
x<=2:
x=2=y-> y=2 or y=2+0x
2x-3y>=4:
2x-3y=4
2x-4=3y
(2/3)x-(4/3))=y
y=(2/3)x-(4/3)
x+y>0:
x+y=0
y=-x or y=-x+0
