Converting Standard Form to Slope Intercept Form

What is the standard form of a linear equation?

• y = mx + b

• ax + by = c

• x = my + b

• ax - by = c

Why do we convert linear equations from standard form to slope-intercept form?

• To make them easier to graph

• To solve for x

• To find the y-intercept

• To eliminate fractions

In Example 1, what is the first step to isolate y?

• Add 2x to both sides

• Divide both sides by 2

• Subtract 2x from both sides

• Multiply both sides by 2

What is the slope of the line in Example 1 after converting to slope-intercept form?

• -2

• -3

• 2

• 3

In Example 2, what operation is performed to move 4x to the other side of the equation?

• Multiply by 4

• Add 4x

• Divide by 4

• Subtract 4x

What is the y-intercept in Example 2 after converting to slope-intercept form?

• -6

• 6

• -30

• 30

In Example 3, what is the coefficient of x after converting to slope-intercept form?

• -3

• 3

• -1/3

• 1/3

What is the y-intercept in Example 3 after converting to slope-intercept form?

• -12

• 12

• 4

• -4

In Example 5, what is the slope of the line after converting to slope-intercept form?

• -4

• -1

• 1

• 4

What is the y-intercept in Example 6 after converting to slope-intercept form?

• -14
