Remember, to check feedback that I amleaving you on every assignment: • Grade Book • Find the Mastery/Nonmastery and click that “grade” • Click Mastery/Nonmastery again • Look below each question for feedback if you had to answer yourself • Look at the bottom of the top blue box (header) if it was multiple choice
Quick facts for Linear Equations• If 0 is in the numerator, then the slope is 0.• If 0 is in the denominator, then the slope is Undefined.
Quick facts for Linear Equations• Horizontal lines are y = # , so you need use the y value in (x, y)• Vertical lines are x = # , so you need use the x value in (x, y)
Quick facts for Linear Equations• To find the y-intercept, let x = 0. Solve for y.• To find the x-intercept, let y = 0. Solve for x.
Quick facts for Linear Equations• An x = # is parallel to an x = #• A y = # is parallel to a y = #• An x = # and y = # are perpendicular
Quick facts for Linear Equations Point-Slope form y – y1 = m(x –x1) simplifies to Slope-Intercept Form (y = mx + b)
