y = k/x of xy = k where k is a constant.
To determine if a relationship represents direct or inverse variation, examine how the variables change in relation to each other. In direct variation, as one variable increases, the other also increases (e.g., ( y = kx ), where ( k ) is a constant). In inverse variation, as one variable increases, the other decreases (e.g., ( y = \frac{k}{x} )). You can also look for a constant ratio or product; in direct variation, the ratio ( \frac{y}{x} ) is constant, while in inverse variation, the product ( xy ) is constant.
It can look like any algebraic equation.
An equation has an equal sign, a expression does not.
You just simply flip the fraction or number. Example: The inverse of 2 is 1/2 and vice versa
A linear equation looks like a straight line, it sometimes does slope, but it is straight.
A hyperbola.

i really don't know maybe you should look it up somewhere else

Oh, dude, direct variation is when two variables change in the same way. In this case, 5x + 3 = 8y + 3, so technically they are changing in the same way by adding 3 to both sides. So, yeah, I guess you could say it's a direct variation, but like, who really cares, right?
Your mom...0.0
A quadratic equation looks like bow.
It can by a polynomial of degree 2 or more, eg y = ax4 + bx3 + cx2 + dx + e Or inverse: y = a/x + b Or power: y = a*bx Or trigonometric: y = sin(ax + b) etc, etc
tu puta madre!
The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
