Question 250727
Ok..a linear equation is expressed by the following y = mx + b

with x and y being the pair cordinates, m = slope and b is the y-intercept (the point where the line crosses the y axis and x = 0)

the standard form is expressed by the following Ax + By = C

These forms can be converted back and forth with simple algebra.

What you will need to graph the line is at least two points.  So the easiest way to do the is pick a x and solve for y. I always pick x to be -1, 0 or 1

For example:

if your equation is y = 3x + 2  if I say x = 0, then:

y = 3(0) + 2
y = 2           
so your first pair would be (0, 2)

then use x = 1
y = 3(1) + 2 
y = 3 + 2
y = 5
then my second pair would be (1, 5)

If I put those on a graph and connect the two points with a line..I have now graphed the linear equation..

Hope this helps
