Rewriting Linear Equations in Slope-Intercept Form

The video tutorial demonstrates how to convert equations into slope-intercept form (y = mx + b). It provides two examples: the first equation is 2X + 4Y - 8 = 2, and the second is -5X + 10Y = 25. The instructor explains each step, including moving terms, combining like terms, and dividing to isolate the variable Y. The tutorial highlights how to identify the slope (m) and the Y-intercept (b) from the final equation form, making it easier to understand the line's characteristics on a graph.

What is the first step to rewrite an equation in slope intercept form?

• Subtract 2x from both sides

• Add x to both sides

• Subtract x from both sides

• Divide all terms by the coefficient of y
