Answer:
D) 5
Step-by-step explanation:
Perpendicular lines have opposite reciprocal slopes.
The line: 
has a slope of 
as it is in y=mx+b form, where m is the slope, and b is the y-intercept.
Since the slope is , we see that the negative reciprocal slope is 
, as 
is the reciprocal (flip the numerator and denominator).
From here, we can use point slope form: 
, where 
is the point. In this case, (3, 1) is the point.
Thus, we have: 
as our final equation.
Simplifying: 
And: 
, which gives us the y-intercept to be 5.
Let me know if this helps!
Nathaniel is correct. fractions are rational numbers

1. $2.78
2. If it’s 20% off you save 13.90 so 69.50- 13.90 is $55.60
120 + 32x < = 720....with x being the number of seats
32x < = 720 - 120
32x < = 600
x < = 600 / 32
x < = 18.75
