Slope Lesson

Understanding Slope-Intercept Form

Concept 1180

Slope-Intercept Form

• Always has Y by itself

• If Y is not by itself then use PEMDAS backwards (SADMEP) to get it by itself

• Do NOT leave Y negative (-y=3x+4)

SLOPE-Intercept Form

• M is just a placeholder for our slope

• Sometimes there is no slope and there is NOTHING there

• M or Slope can be a whole number but always graphed out like a fraction (RISE/RUN)

• Every whole number as a fraction is that number over 1

Slope-INTERCEPT Form

• B is the place holder for the intercept

• This is where the line crosses the Y-Axis

• When graphing the line always start here when it's in this form

• Place a dot on the Y-Intercept and count your slope (Rise//Run) from there

Multiple Choice
