Understanding Formulas

Which formula is used to find the slope of a linear function?

• m = (y₂ - x₂) / (y₁ - x₁)

• m = (y₂ - x₁) / (y₁ - x₂)

• m = (y₂ - y₁) / (x₂ - x₁)

• None of these

Which is the

formula for Standard Form?

• Ax + By = C

• y - y₁ = m(x - x₁)

• y = mx + b

Which is the

formula for Point-slope?

• Ax + By = C

• y - y₁ = m(x - x₁)

• y = mx + b

Which is the

formula for Slope-Intercept Form?

• Ax + By = C

• y - y₁ = m(x - x₁)

• y = mx + b

What formula is given?

• point-slope form
• slope-intercept form
• slope of a line
• standard form of a line

Which value is the slope in the equation:

y= 4x + 2

• 4

• 2

• x

Which value is the y-intercept in the equation:

y= 2x -2

• 2

• -2

• 1

The y intercept is AWESOME! It helps us to know...

• Where our line will end.

• If our line is positive or negative.

• Where to start graphing our line.

If you have a slope of 1/2 that means you could...

• Go up 1 and right 2 units.

• Go right 1 and up 2 units.

• Go down 1 and left 2 units.

• Go left 2 and down 1.
