Solving for y in Slope-Intercept Form

The video tutorial explains how to convert equations into slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. It provides step-by-step solutions for ten different equations, demonstrating how to isolate y and identify the slope and y-intercept. The tutorial also covers techniques for reducing fractions using a calculator.

What is the slope-intercept form of an equation?

• ax + by = c

• y2 - y1 = m(x2 - x1)

• x = my + b

• y = mx + b
