Step-by-step explanation:

x =7y ----(1)

xy=252 ----(2)

(1) into (2):

(7y)(y) = 252

$7 {y}^{2} = 252 \\ 7y = \sqrt{252}$

7y=15.874....

y=2.27

y value into (1)

x= 7(2.268)

x=15.87

the two numbers are 15.87 and 2.27 (Ans)

Answer:

y = 3x +4

Step-by-step explanation:

The equation for the parallel line will have the same x- and y-coefficients, but a different constant. You can put the given point values into the equation to see what the constant needs to be:

y = 3x + b

10 = 3·2 + b . . . . . . substitute x=2, y=10

4 = b . . . . . . . . . . . . subtract 6

The equation of the line is ...

y = 3x +4
