Straight line graph

A straight line graph is a visual representation of a linear function. Equations of other straight line graphs The equation of a straight line on a graph is made up of a y term an x term and a number and can be written in the form of y mx c.

Calculating The Slope Of A Straight Line Calculating Slope Straight Lines Line

You can identify a straight line graph from looking at the terms in the equation.

. Any function of the form y mxb where m and b are constants will have a. When straight-line graphs are vertical the equation for the line. Start by creating a table of values choosing values of x to substitute in to the equat.

Calculate the Straight Line Graph Calculate the Straight Line Graph If you know two points and want to know the ymxb formula see Equation of a Straight Line here is the tool for you. Watch this video to discover how to plot straight lines onto a graph. Straight line graphs y mx c is an important real-life equation.

The graph is a nice straight line going uphill which was to be expected because the equation has a positive slope value of m 3 and crossing the y -axis at the y - intercept value of b 2. Their graphs are straight lines. The gradient m represents rate of change eg cost per concert ticket and the y-intercept c represents a starting value eg.

When straight line graphs are horizontal the equation for the line will start as y a certain number such as y 3 or y 5. The comment about x and y taking any value. Displaying all worksheets related to - Straight Line Graphs Grade 9.

A straight line is a figure formed when two points A x 1 y 1 and B x 2 y 2 are connected with minimum distance between them and both the ends extended to infinity. 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.
