Different Forms of Linear Functions

Which of the following is the slope-intercept form?

• m = (y₂ - y₁)/(x₂ - x₁)

• y = mx + b

• y - y₁ = m(x - x₁)

• ax + by = c

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

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

• y=kx

Write the equation in point-slope form of the line that passes through the given point and has the given slope.

(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y + 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)
