1. In the equation y = 2x, what would be the C. O.P ?
2. A graph has the points (2,6) ; (3,9) ; and (5,15)
What is the equation of the graph?

9514 1404 393

Step-by-step explanation:

1. Match the given equation (y = 2x) to the pattern ...

  y = kx . . . . . k is the constant of proportionality

Hopefully, you can see that k corresponds to 2. That is, the coefficient of x is the constant of proportionality. It is 2.

2. Since you're studying proportions, it is useful to look at the ratio of the y-value to the x-value. In each case, it is 6/2 = 9/3 = 15/5 = 3. Then the graph shows the variables are proportional, with a constant of proportionality of 3.

  y = 3x

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
