The slope of the parallel line is -6/7
the slope of the perpendicular line is 7/6
the slope of the line = -6/7
the gradient of two parallel lines are equal
the product of the gradient of two perpendicular lines is -1
: the gradient m1*m2 = -1
m2= -1(-6/7)
m2= 7/6
Answer:
The correct answer is B. The number of rides and the total cost are both dependent variables, as both depend on the amount of money that Nia has.
Step-by-step explanation:
The total cost is dependent because it relies on how many rides Nia takes, and the $19.50 limit.
The number of rides is dependent on the limit of $19.50 because the $19.50 is the limit and the total amount of rides is locked by $19.50
I'm not sure, though.
Line l:
1 = - 2 m + b / + ( - 1 )
1 = 4 m + b
----------------------
- 1 = 2 m - b
+
1 = 4 m + b
--------------------
0 = 6 m; m = 0
1 = 0 + b, b = 1
Line l:
y = 1
The distance from point P to line l:
7 - 1 = 6
Answer: 6 units.
