What is Linear Equation
Ways Of Write Linear Equation
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form.

Slope is a surface of which one end or side is at a higher level than another;

Y-Intercept in a Real World Scenario You have 300 items of clothing and decide to start donating to Goodwill. Your y-intercept is the amount of clothing you have before you start donating to Goodwill every month.

What is Standard Form


Simultaneous Equations  is equations involving two or more unknowns that are to have the same values in each equation.

Slope Intercept

Rule 

  • m can be positive or negative 
  • b (y - intercept ) can be positive or negative          
Problem   
y =  x
(note: this could be rewritten as )
