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)

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

• y - y₁ = m(x - x₁)

• Ax + By = C

• y = mx + b

• y=kx

Which of these represents standard form of a linear equation?

• y - y₁ = m(x-x₁)

• Ax + By = C

• y = mx + b

• y=kx

Find the x and y intercepts

5x - 3y = 15

• x intercept is 3

  y intercept is 5

• x intercept is -3

  y intercept is 5

• x intercept is 5

  y intercept is -3

• x intercept is 3

  y intercept is -5

Change the following equation to slope intercept form:

y + 2 = -3(x - 5)

• y = -3x + 17

• y = -3x + 13

• y = -3x - 13

• y = -3x - 17
