Solving for 'y' in Slope-Intercept Form

In this algebra tutorial, Mr. Guy Love demonstrates how to solve equations for y to express them in slope-intercept form. The video covers two examples: first, solving 5x - 3y = 12, and then tackling a more complex equation, 6x - 3y = 5x + 2y + 7. The tutorial explains each step in detail, including combining like terms and isolating y, and highlights the importance of understanding slope and y-intercept in the context of y = mx + b form.

What is the first step in solving the equation 5x - 3y = 12 for y?

• Add 5x to both sides

• Subtract 5x from both sides

• Multiply both sides by 3

• Divide both sides by 5
