Slope of Equation Point Slope Form

Which of these represents point-slope form of a linear equation?

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

What is the equation in Point-Slope form of the line that goes through the point (6,1) and has a slope of -3?

• y - 6 = -3(x - 1)

• y + 6 = -3(x + 1)

• y - 1 = -3(x - 6)

• y + 1 = -3(x + 3)

Write the equation in point-slope form

Write the equation of the line in Point-Slope form that goes through the point (10,5) and has a slope of -3

• y - 5 = -3(x - 10)

• y= -3x + 35

• y + 5= -3(x + 10)

• y= -3x - 35

Why might a person use a point-slope formula?

• The graph's has no slope

• The graph's line does not cross the y-intercept

• The graph's line does not cross the y-intercept at a whole number (easy to work with)

• The graph does not any a (x, y) points
