Finding Slope and Y-Intercept

The video tutorial explains how to find the slope and y-intercept of a linear equation in two variables. It introduces the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. The tutorial provides examples to demonstrate how to rearrange equations into this form and identify the slope and y-intercept. It covers solving for y and isolating variables to achieve the slope-intercept form, emphasizing the importance of ordered pairs for y-intercepts.

What is the main goal when finding the slope and y-intercept from a linear equation?

• To find the slope and y-intercept

• To determine the x-intercept and y-intercept

• To find the slope and x-intercept

• To solve for the variable x
