You can take apart the word ‘perpendicular bisector’:
Perpendicular means at a right angle to the line.
So you would find the gradient of your line segment, assuming you were given two points along the line. Then find the negative reciprocal of this gradient to get your new gradient.
Bisector means cut in half.
So you find the midpoint of your line segment.
Now, substitute the midpoint coordinate and your new gradient into the equation of a straight line.
Hope this helps :D
Answer: B
Step-by-step explanation: the first number is a negative so it’s less than the second number
1500 + 0.45x < 1.70x
1500 < 1.70x - 0.45x
1500 < 1.25x
1500/1.25 < x
1200 < x.....so she would have to sell 1201 cards to make a profit
Answer:

Step-by-step explanation:
