Answer:
Step-by-step explanation:
Basically -1/2 is the slope meaning you go down 1 and go to the right by 2 and then the -2 is the y-intercept meaning when x=0 y=-2
I think it might be the 3rd one.

Answer:
A. Perpendicular
Step-by-step explanation:
Lines are perpendicular if their slopes are opposite reciprocals of each other. Opposite, meaning if positive, the other slope is negative, and if negative, the other slope is positive. Reciprocal meaning, the number is flipped upside down, turning fractions into whole numbers and vice versa.
1/9
-1/9
-9
The slopes are perpendicular
2 lines parallel, and 2 triangles have a common angle
So the smaller Δ is similar to the bigger Δ (AA Similarity)
9:(4x-2)+9=12:(3x+2)+12
9:4x+7=12:3x+14
9(3x+14)=12(4x+7)
27x+126=48x+84
21x=42
x=2
So the answer is x=2
