Q:
# What Is 3x/4?

**Y=3x/4 is an algebraic straight-line equation.** X represents the horizontal axis, or domain, and Y represents the vertical axis, or range. The value of Y depends on X and vice versa. One can calculate the value of the unknown variable by using algebraic operations.

For example, to calculate the value of Y when X is 3, first insert the numerical value of X into the equation: Y=3*3/4. The simplified equation reveals that Y equals 9/4, or 2.25. Continue to solve for Y to establish a linear progression of points. The X and Y points can be plotted on a graph as dots, and a straight line can be drawn through them. Graphing calculators can perform these functions automatically.
