To graph a linear equation, one must first simplify it into the slope-intercept form, y=mx+b, where m is equal to the slope of the line. Next, one must find the x and y coordinates. By making x equal to zero the equation can be simplified into y=b, giving the coordinate (0,b). Plot this point on your graph. By making y equal to zero, the equation becomes x=[(-b)/m], giving the coordinate ([(-b)/m], 0). Plot this point on your graph. Once you have both coordinates marked, simply connect these two points with a line.

Definition of linear equations?

A linear equation an equation whose graph is a line. A linear equation is made up of two expressions set equal to each other.


How can the degree of the equation tell us if the equation is linear or not?

A linear equation always has a degree of one because the slope has to be constant to form a line. So, x + 7 is linear, 7 - x is linear, 4x - 3.7 is linear, but anything with x2 , etc. is not linear.
