## What if a graph has a straight line?

The formal term to describe a straight line graph is linear, whether or not it goes through the origin, and the relationship between the two variables is called a linear relationship. Similarly, the relationship shown by a curved graph is called non-linear.

### What is the equation of a line that is straight?

y = mx + c

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

#### Is a straight line linear?

The term linear function we use on a daily basis is perfectly correct in terms of calculus. In this context, every straight line is a linear function.

**What is equivalent to ax by C?**

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it’s pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

**What does C mean in ax by C?**

Alan P. Jun 1, 2015. Ax+By+C is a generalized form (in fact the standard generalized form) for a linear equation. where A,B,andC are placeholders for constants (the x and y are variables).

## How do you find the equation of a line in a graph?

To find the equation of a graphed line, find the y-intercept and the slope in order to write the equation in y-intercept (y=mx+b) form. Slope is the change in y over the change in x. Find two points on the line and draw a slope triangle connecting the two points.

### What is the form Ax By C 0?

Any equation of the form Ax + By + C = 0 (i.e. a linear equation in one or two variables), will represent a straight line on the XY plane, where A and B should not be both zero.
