Answer: Perpendicular.
Step-by-step explanation:
Suppose that you have two perpendicular lines:
Remember that a line is something like:
y = a*x +b
and two lines are parallel if they have the same slope (a) but a different y-intercept(b)
Then our lines can be:
y1 = a*x + b1
y2 = a*x + b2.
Now, if we have a line:
y = a*x + b
Then a perpendicular line will have a slope equal to -(1/a):
yp = (-1/a)*x + c
So this only depends on the slope, and we know that our two parallel lines have the same slope. So if we construct a transversal line that is perpendicular to one of our lines, it also must be perpendicular to the other line.

Step-by-step explanation:
Let the cost of the boogie board be represented by x.
The surfboard cost six times the boogie board. Therefore, surfboard =6x
The wetsuit is $300 less than the surfboard. This means wetsuit = 6x - 300
Together a boogie board, surfboard, and wetsuit cost $1,312. Therefore,
x + 6x + 6x - 300 = 1312
13x = 1312 + 300
13x = 1612
x= 1612 / 13
x = 124
Boogie board cost $124
Surfboard = 6x
= 6 × $124
= $744
Wetsuit = 6x - 300
= $744 - $300
= $444
