• Ax + By = C

• y = mx + b

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

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

For the equation
y + 1 = -3(x - 5),
the line contains the point (5, -1) and has a slope of?

• -1

• 1

• -3

• 5

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)

Write the equation below in standard form
y = 2/3 x + 5.

• -2/3x+y=5

• -6/3x + 3y= 15

• 2/3x + y = 5

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

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b
