How do you convert an equation from standard form to slope-intercept form?

Back

To convert from standard form (Ax + By = C) to slope-intercept form (y = mx + b), solve for y by isolating it on one side of the equation.

What does the y-intercept represent in a linear equation?

Back

The y-intercept represents the value of y when x is zero, indicating where the line crosses the y-axis.

Front

How can you write a linear equation based on a real-world scenario?

Back

Identify the variables, determine the relationship between them, and express that relationship in the form of a linear equation.
