Math Hack: Graphing Standard Form Equations (Part 2 – Fast Intercept Trick!)
Here’s a math trick for graphing equations in standard form (Ax + By = C) without wasting time! In this video (Part 2 of my Standard Form series), I’ll show you how to graph by intercepts, when to switch to slope-intercept form, and how all 3 forms of linear equations connect. This hack makes graphing standard form equations quick, clear, and stress-free—perfect for algebra homework, quizzes, or review!
This video is Standard Form Part 2; it describes how to graph equations in standard form "ax + by = c" by: graph by intercepts. It also addresses when graph by intercepts does not work and how to adjust.
This video also stresses the importance of identifying the different forms of linear equations.
Need to know: on the x-axis, y = 0. And on the y-axis, x = 0.
1. To find the x-intercept: replace the "y" with 0. Simplify and Solve.
2. To find the y-intercept: replace the "x" with 0. Simplify and Solve.
3. Plot the two points, draw a line through them.
Faster?
1. x-intercept: Divide the number by the number in front of the x (coefficient)
2. y-intercept: Divide the number by the number in front of the y (coefficient)
3. Plot the two points, draw a line through them. Done
This video could work for #Algebra students who were absent, or in a flipped classroom.
