Yes. A fraction is still a number after all.
Application: say you have y=(1/2)x+6, the slope is 1/2 so you start at 6 on the y-axis and go up one and over 2 and you have your next point (x=1). It's the same thing as saying the value of x is being divided by 2. If you can multiply x by a number, why can't you divide?
a more complex one would be y=(3/4)x+9 in which case, you're both multiplying and dividing. You're multiplying x by 3 and dividing that by 4.

When can you say that the equation is linear?
An equation is linear when it contains only variables of degree 1 and constants. ALL linear equations will be of the form: a1x1+a2x2+a3x3+...+anxn=c where an and c are constants.
What is the difference between a linear equation and an quadratic equation?
A linear equation, when graphed, is always a line. A quadratic is a curve. Also, linear equations are of the form y=mx+b where m and b are arbitrary constants and quadratics are y=(x^2) +mx +b where m and b are arbitrary constants.
Is y equals 5x3 plus 6 linear?
y = 5x3 + 6 is a cubic equation, not a linear equation. Linear equations contain only terms of degree 0 (i.e. constants) and terms of degree 1.
Where the given equations are not linear?
Equations are not linear when they are quadratic equations which are graphed in the form of a parabola
How does the method for solving equations with fractional or decimal coefficients and constants compare with the method for solving equations with integer coefficients and constants?
The method is the same.
