Linear equations, inequalities, systems and functions

Every lesson's first step is free. Your stars need an account.

1. 1Translate a situation into an equationName each number's job, then write the equation11 min
2. 2Interpret terms, constants, and pointsGive every number its unit, and the unit names it10 min
3. 3Solve linear equations for a targetRead the target first, then stop when it stands alone9 min
4. 4Zero, one, or infinitely many solutionsCompare slopes and intercepts instead of solving10 min
5. 5Solve a system of two linear equationsCancel one variable, then answer what's asked10 min
6. 6Build a linear function from two factsSlope from the change, intercept from one point10 min
7. 7Use slope and intercept relationshipsRead the slope first, then apply one rule10 min
8. 8Evaluate, invert, and transformFind the missing end, then let the slope carry changes10 min
9. 9Model and optimize with inequalitiesWrite the limit, solve at its edge, round to what fits10 min
10. 10Rearrange a literal equationSolve for one letter as if the rest were numbers10 min
