Equations of lines come in several different forms two of those are: slope-intercept form where m is the slope and b is the y-intercept. How to write math equations math sandbox if you would like to experiment writing math equations, enter your equation in the text field or edit an existing equation. Most of the time when someone says “word problems” there is automatic panic but word problems do not have to be the worst part of a math write an equation. Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis to write an equation in.
I need an easy and helpful way to teach writing equations example: how to set up algebraic equations to match word problems students often have problems setting up an equation for a. Purplemath straight-line equations, or linear equations, graph as straight lines, and have simple variable expressions with no exponents on them. Covers the 'point-slope' form of linear equations, including how to find a line equation using this form. An equation is a mathematical sentence containing an equals sign it tells us that two expressions mean the same thing, or represent the same number an equation can contain variables and.
