SLOPE INTERCEPT FORM:
Used to graph linear functions.
Shows us the slope and y-intercept.
Used for GRAPHING linear functions.

slopeinterceptform

m = Slope (how steep the line is)

b = the Y Intercept (where the line crosses the Y axis)\

y=mx+b graph

POINT SLOPE FORM:
Used for linear functions.
Shows us the slope and 1 point on the graph.
Used when you have the slope and 1 point to find the y-intercept.

psform

m=slope
x1=x coordinate from the point
y1=y coordinate from the point

STANDARD FORM:
Used for linear functions.
Used when solving for x or y, when you have 2 equations.
Used to solve systems of linear equations (next unit).
