What's the equation exactly?
Answer: 22.4
Explanation:
The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.
The first chord has pieces of 10 and x, which multiply to 10*x
This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)
10*x = 14*16
10x = 224
x = 224/10 ... divide both sides by 10
x = 22.4
A (−3, 1) and B (3, 4)
2 Let A have coordinates (x1, y1). Let (x1, y1) = (−3, 1).
3 Let B have coordinates (x2, y2). Let (x2, y2) = (3, 4).
4 Find the length AB by applying the
formula for the distance between
two points.
AB = "(x2 − x1)2 + (y2 − y1)2
= "[3 − (−3)]2 + (4 − 1)2
= "(6)2 + (3)2
= !36 + 9
= !45
= 3!5
= 6.71 1
Is the the line veritcal or horizontal,if its vertical then the slope is undefined, if its horizontal then it should be zero leading to y=4÷9 or y=0.44
