Write the slope intercept form of a line that passes through the points (5, 1) and (0,0)

Write your answer without any spaces.

• m = -4/3

• m = -3/4

• m = 4/3

• m = 3/4

Write a linear function f with the given values f(6) = 2  and   f(9) = 5.

• f(x) = -x - 6

• f(x) = x - 6

• f(x) = -x - 4

• f(x) = x - 4

Determine whether the given lines are parallel, perpendicular, or neither. Explain why

Line a: y = 3x - 7

Line b: y = 3x + 1

• Parellel, because the slopes are the same

• Perpendicular, because the slopes are the same

• Neither, becuase they have different y-intercepts

• Parellel, because the slopes are opposite recipricals of each other

• Perpendicular, because the slopes are opposite recipricals of each other

Determine which lines, if any, are parallel or perpendicular. 

Line A  passes through (-2, 1) and (0, 3)

Line B passes through  (4, 1) and (6, 4)

Line C passes through  (1, 3) and (4, 1)

• Line A and C are perpendicular to each other

• Line B and C are perpendicular to each other

• Line A and C are parallel to each other

• Line B and C are parallel to each other

• Line A, B, and C are all paralell to each other

• The student incorrectly found the y -intercept, it should have been y=-4x + 4

• The student incorrectly stated the slope was by stating it was negative 4, it should have been y = 4x+7

• The student changed the slope to the "opposite reciprical" of -4, when they should have kept the slope the same due to the lines being parallel.

• The student incorrectly placed the x and y coodinates in the point slope formula, it should have been written

  y - 1 = -4(x - 3)

• There is no error in the algebraic work done by this student.
