Slope Intercept Word Problems Challenge

This video tutorial covers the slope-intercept form of linear equations, focusing on writing equations, understanding initial values, and solving word problems. It includes warm-up exercises, real-world examples, and practice problems to reinforce learning. The tutorial also explains how to interpret the slope and y-intercept in various contexts, such as graphs and tables.

What is the format of the slope-intercept form equation?

• x = my + b

• y = bx + m

• x = by + m
