Yes, this is an example of direct variation.
A:
This is a direct variation because both are in the numerator of a fraction and on opposite sides of the = sign. If they are both on the same side of the equals sign, then one would have to be in the numerator and the other in the denominator for them to be a direct variation.
Multiply the bottom equation by -1
It is: y = -1/5x-2
y = 5x + 9
No.
a linear equation solution 5x-37=13 5x=13+37 5x=50 x=10
Multiply the bottom equation by -1
It is: y = -1/5x-2
5x-4y=8
To find out what 5x equals to, you have to post the rest of the equation.
y = 5x + 9
x = 6.6
Write out equation - 10y - 5x= - 20 Negate equation 10y + 5x = 20 Isolate y variable 10y = - 5x + 20 Divide equation by 10 y= -1/2x + 2
No.

5x 2y = 10
In the equation 43X +2=5X, X=-1/19.
