Exploring Adding and Subtracting Rational Expressions

The video tutorial covers the slope-intercept form of a linear equation, represented as y = mx + b, where m is the slope and b is the y-intercept. It explains how to write equations using given slope and intercept values and demonstrates how to identify these values from graphs. The tutorial includes multiple examples to illustrate these concepts, emphasizing the importance of simplifying slopes and understanding the graphical representation of linear equations.

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

• Coefficient of y

• Slope

• X-intercept

• Y-intercept
