Point Q is 3 units up and 4 units to the right from Point P. From this, you know the slope is 3/4 (rise over run = slope).
Substitute one of the points in to the equation y = 3/4x + b
For example, substitute Point (2, 1).
1 = 3/4(2) + b
b = -1/2
y = 3/4x -1/2
Match the format of the question:
4y = 3x -2
4y - 3x + 2 = 0
Answer D
Substitute one of the points in to the equation y = 3/4x + b
For example, substitute Point (2, 1).
1 = 3/4(2) + b
b = -1/2
y = 3/4x -1/2
Match the format of the question:
4y = 3x -2
4y - 3x + 2 = 0
Answer D
