statement is true?
2 answers:
Answer:
Option B is the answer.
Step-by-step explanation:
From the graph given in the picture we will find the value of one bracelet.
then we will find the value of one book from the given table.
Finally we will compare the prices of both to find the relation.
From graph we see line is passing through points (4, 14) and (0, 0)
So the slope of the line will represent the price of one bracelet.
Slope =
It reveals price of one bracelet = $3.5
Now from the table 2 books are costing $7.
So 1 book will cost =
Finally we find that cost of books is same as the cost of the bracelets.
Therefore Option B. is the answer.

Answer: y = + 30/11
Step-by-step explanation:
Two line are said to be perpendicular to each other if the slope of the first line = -1 / the slope of the second line , that is
If the slope of the first line is M1 and the slope of the second line is M2 , then M1 = -1 / M2.
From the equation given , M1 = - 11 , that means M2 = 1 / 11
Using the formula y - y1 = m ( x - x1) to calculate the equation , we have
y - 3 = 1/11 ( x - 3)
Multiply through by 11 , we have
11 ( y - 3 ) = x - 3
11y - 33 = x - 3
11y = x + 30
y = x/11 + 30/11
