Exploring Slope-Intercept Form and Proportional Relationships

This video tutorial covers linear relationships, focusing on slope-intercept form. It explains how to find the slope and y-intercept from graphs and tables, solve word problems using linear equations, and understand proportional relationships. The tutorial also demonstrates solving systems of equations using graphs.

What does the 'm' in the slope-intercept form represent?

• The maximum value of y

• The slope of the line

• The x-intercept

• The y-intercept

How do you find the slope in a table?

• Dividing y2 by y1 and multiplying by x2 over x1

• Subtracting y2 from y1 and dividing by x2 minus x1

• Multiplying y2 by y1 and dividing by x2 times x1

• Adding y2 to y1 and dividing by x2 plus x1
