[ x = 5 ]
[ y = 1 ]
That's a single point.
If you want to see how 'x' and 'y' behave when there's some "variation", then you
have to let them vary. That means you have to look at more than one point.
No, it is not a direct variation.
what is the constant variation of k if x=.5 and y=1
y = kx k = y/x = 21/-5 = - 21/5
Y=kx+m Y=-5x+m K=-5

It means if it is the constant rate of a number kind of like a direct variation. Like if you say 10 divided by 5 it equals 2 and if you say 4 divided by 2 it equals 2 so that's constant I hope I could help you
y = kx k = y/x = 21/-5 = - 21/5
It is 5.
Y=kx+m Y=-5x+m K=-5
If P varies directly with q, r and s then P = kqrs, where k is a constant. As 70 = k x 7 x 5 x 4 = 140k : k = 70/140 = 1/2 The equation of joint variation is P = ½qrs.
If y varies directly as x then k = 2.
The equation is xy = 5*9 = 45 Alternatively, y = 45/x
