Math, Algebra. 271 questions
Work with equations like 2x + 3y = 12: their graphs, slope, intercepts and what they mean in context.
What this skill tests
- Slope and intercepts
- Standard and slope intercept form
- Interpreting a line in a real situation
How to approach it
- 1Rewrite in y = mx + b form when you need the slope or the y intercept.
- 2In word problems, the slope is the rate and the intercept is the starting value.
- 3Graph the equation in Desmos to check intercepts quickly.
