Is 2x 3y 7 a linear function?

3. In particular, the set of solutions to 2x - 3y = 7 is a straight line. (This is why it's called a linear equation.)

Also question is, how do you determine if something is a linear equation?

A linear function is in the form y = mx + b or f(x) = mx + b, where m is the slope or rate of change and b is the y-intercept or where the graph of the line crosses the y axis. You will notice that this function is degree 1 meaning that the x variable has an exponent of 1.

Likewise, how do you know if a table is linear or nonlinear? You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear.

Also asked, how do you tell if an equation is linear or nonlinear?

Using an Equation Simplify the equation as closely as possible to the form of y = mx + b. Check to see if your equation has exponents. If it has exponents, it is nonlinear. If your equation has no exponents, it is linear.

How can you tell if a function is linear without graphing?

To determine if an equation is a linear function without graphing, you will need to check to see if your function has the characteristics of a linear function. Linear functions are first-degree polynomials. Check that the y, or independent variable, is by itself on one side of the equation.
