Answer:
x = 1
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
here k = 8, thus
y = 8x ← equation of variation
When y = 8, then
8x = 8 ( divide both sides by 8 )
x = 1
Answer:
(4, 3 ) and (4, - 3 )
Step-by-step explanation:
A distance of 5 units from the origin represents the hypotenuse of a right triangle with sides 3- 4 - 5
If the x-coordinate is 4 then the y-coordinate is | 3 | = ± 3
the coordinates are (4, 3 ) and (4, - 3 )
