Answer:
50
Step-by-step explanation:
I took the test
The midpoint of 18.6 and 18.5 is 18.55
Consider the number as 'n' (for now)
3n - 9 = 69
3n = 69 + 9
3n = 78
n = 78/3
n = 26
Therefore, The number is 26
Since the slope is rise/run, 1/6 goes up one, right 6. Perpendicular is opposite that. so a slope of -6 goes down 6 and right 1. (as a fraction it's -6/1)
Y=7x+3
They are parallel so the slope is the same and plug in the two coordinates to get the y intercept. This gives you y=7x+3
