What is slope-intercept form?
y=mx+b
Ax+By=C is used for what?
Finding the Y and x Intercept
it is Standard Form
Y=mx+b is used for what?
Find the slope and y-intercept
it is called Slope-intercept form
y-y1=m(x-x1) used for
When given a point and a slope, or 2 points
It is called point-slope-form
What is the order you put the equations for writing the equation of a line?
point-slope, Slope int, standard
(y-y1)=m(x-x1), y=mx+b, Ax+By=C
What is a Consistent?(independent)

What is a consistent system? (dependent)
Meet at every point, dependant
What is substitution?
