What is the equation of the line that passes though the point (4, -3) and has slope of 3?

• y = 3x - 7

• y= 3x - 15

• y = 3x - 7

• y = 3x + 7

Which equation represents the line that passes through points

(2, 0) and (-2, 4)?

• y = -x + 2

• y = x - 2

• y = 4x + 2

• y = 2

Two points are shown on the line in the graph. What is the equation of the line?

• y = 2x - 2

• y = 1/2 x + 2

• y = 2x + 1

• y = 2x + 2

Two parallel lines are cut by a transversal, as shown. What is the solution for x, and why?

• x = 17. because corresponding angles are equal.

  Therefore 3y + 53 = 7y - 55

• x = 27, because alternate exterior angles are equal.

  Therefore 3y + 53 = 7y - 55

• x = 22, because interior angles are equal..

  Therefore 3y + 53 = 7y - 55

• x = 24, because vertical angles are equal.

  Therefore 3y + 53 = 7y - 55

Two parallel lines are cut by a transversal as shown. Solve for x. Then explain your reasoning.

• x = 3, because alternate interior angles are congruent.

  Therefore 8x - 12 = 4x

• x = 16, because alternate interior angles are congruent.

  Therefore 8x - 12 = 4x

• x = 8.5, because corresponding angles are congruent.

  Therefore 8x - 12 = 4x

• x = 3, because vertical angles are congruent. Therefore 8x - 12 = 4x

In each diagram, line g is parallel to line k, and line t intersects lines g and k. Based on the diagrams, which statement about x is true?

• The value of x is 136, because the labeled angled in each diagram are congruent.

• The value of x is 180, because the labeled angles in each diagram are supplementary and the sum of the measures of the supplementary angles is 180 degrees

• The value of x is 44, because the sum of the measures of the labeled angles in each diagram is 180 degrees

• The value of x is 44, because the sum of the measures of the labeled angles in each diagram is 180 degrees
