Exploring Standard Form of Linear Equations

The video tutorial explains the standard form of linear equations, which is expressed as ax + by = c, where a, b, and c are integers. It describes two methods for graphing from standard form, focusing on converting it to slope-intercept form (y = mx + b) to find the slope and y-intercept. The tutorial provides step-by-step instructions on rearranging equations and graphing them on a coordinate plane, including examples to illustrate the process.

What is the standard form of a linear equation?

• x^2 + y^2 = r^2

• y = ax^2 + bx + c

• ax + by = c

• y = mx + b

What are integers?

• Fractions

• Negative numbers

• Decimals

• Whole numbers

What is the first step in converting a standard form equation to slope-intercept form?

• Multiply both sides by x

• Divide both sides by y

• Subtract the x term from both sides

• Add the x term to both sides
