3.4 Review (Day 1)

What is the equation to find slope?

• y = mx + b

• y - y1 = m(x - x1)

• Ax + By = C

• y2 - y1 / x2 - x1

What is the equation for point-slope form?

• y = mx + b

• y - y1 = m(x - x1)

• Ax + By = C

• y2 - y1 / x2 - x1

What is the equation for slope-intercept form?

• y = mx + b

• y - y1 = m(x - x1)

• Ax + By = C

• y2 - y1 / x2 - x1

What is the equation for standard form?

• y = mx + b

• y - y1 = m (x - x1)

• Ax + By = C

• y2 - y1 / x2 - x1

Write an equation in standard form of the line that passes through:

(0, 4) and (2, 8)

Use the point (0, 4) when doing point-slope form

• 2x + y = 4

• -2x + y = 4

• 4x + y = 2

• -4x + y = 2
