Step-by-step explanation:
B.(1,3)
C.(4,6)
D.(3,6)
E.(4,2)
F.(5,10
The following points that are on the line given by the equation y=2x are Options (D). (3,6) and (F). (5,10).
A straight line is a line passing through the x-y plane that has equal intercepts with respect to the x axis and the y-axis. The slope of a straight line is always equal. The straight line is also satisfied by the coordinates points in the x and y axis respectively.
To identify the points satisfied by any given equation, we have to replace the points given in the following equation.
Taking first point in option (A) , (16,8) , we have y = 8 and x = 16 which does not satisfy the equation y = 2x .
Taking second point in option (B) , (1,3) , we have y = 3 and x = 1 which does not satisfy the equation y = 2x .
Now from the following options, checking points in Option (D) where x = 3 and y = 6 which satisfies the equation y = 2x .
Also checking the points in Option (F) where x = 5 and y = 10 which satisfies the equation y = 2x .
The following points that are on the line given by the equation y=2x are Option(D). (3,6) and Option(F). (5,10) .

Answer:the orginal price of the tennis racket is $47
Step-by-step explanation:
Let x represent the original price of the tennis racket at the sports store.
Leah has a 20% off coupon for the sports store. The tennis racket is available at a discount of 10%.
The store applies the coupon after the 10% is taken. The value of the discount on the original price of the tennis racket would be
10/100 × x = 0.1 × x = $0.1x
The discounted price of the racket would be
x - 0.1x = 0.9x
The value of the coupon would be
20/100 × 0.9x = 0.2 × 0.9x = 0.18x
The selling price after the coupon was applied would be
0.9x - 0.18x = 0.72x
She buys the racket for $34. This means that
0.72x = 34
x = 34/0.72 = $47
