Slope- Intercept Form Standard form Point-Slope Form
m =slopeb = y -intercept
1.) Quick for graphing using the slope and y-intercept.2.) Story problems involving a starting amount and a rate.
A,B and C are integers(no fractions!). Variable terms on the left, constants to the right!
1.) Quick for graphing with intercepts.2.) Story problems involving purchases, chemistry mixture problems, "Grocery store equations"
is a point.
m=slope
2.) Easy to create an equation. " Fill in the blanks".

Write an equation in slope-intercept form given a point and the slope.
1. A line passes through ( 2, 5) with a slope of 3/2.hint: "fill in three, find b".
*You can also start with point-slope form and solve for y.
