Best Answer

-- Pick any number at all and call it " x " . Any number whatsoever.

-- Multiply it by 8 and call the product " y " .

-- There you are ! Now you have an ordered pair that's a solution to that equation.

There's no limit. You can keep inventing ordered pairs just like that, until

you have millions or billions of them, or as many as you want.

Q: What orederd pair is y equals 8x?

x=7 and y=4

X= -1/4. Y= -2/5. ( -.25, -0.4 )

Solving by the elimination method: x = 7 and y = 2

7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387

x=4, y=9 (4,9)

No.

x=7 and y=4

-8x-8y=-64 -8y=8x-64 y=-x+8

X= -1/4. Y= -2/5. ( -.25, -0.4 )

Solving by the elimination method: x = 7 and y = 2

If: y = 8x+7 then the y intercept is 7 and the slope is 8

7x+3y=-52 3(8x-y=-74) 7x+3y=-52 24x-3y=-222 7x=-52 + 24x=-222 31x=-274 x=8.8387

Complementary angles add up to 90 degrees so if y = 8x-20 degrees then the complement of y is 90 - (8x - 20) = 110 - 8x degrees.

4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x

x=4, y=9 (4,9)

When 5x+3 = 17 then x = 2.8 Therefore when 8x-y = 3 then x = 2.8 and y = 19.4
