I think it’s the third one but I’m not %100 sure
Y-3=3(x-2)
y-3=3x-6 :-x=0
y-3=0-6
y=-6+3
y=-3
What do you need help with?
Answer:

Step-by-step explanation:

The domain of a function is the set of input values that the function can take.

Answer:
angle 1 is equal to 40°
Step-by-step explanation:
angles 1 and 2 are congruent due to alternate interior angles of parallel lines. This means that 2x+20=3x+10, solving this leaves us with x=10. Since angle 1 = 2x +20 and x=10, solve to get 2(10)+20 =20+20 = 40
