Slope Intercept Form of a Linear Equation | Integrated Math 1 (2026 Update)

Описание: In this lesson we learn how to graph and interpret linear equations in slope-intercept form: y=mx+b where m is the slope (rise/run) and b is the y-intercept (where the line crosses the y-axis).

You’ll practice:
Graphing lines quickly using y-intercept → slope
Finding the equation from a graph (identify m and b)
Finding the equation from two points (use the slope formula, then solve for b)
Interpreting slope and y-intercept in a real-world situation (gift card / coffee example)
