Question

1. What is the equation of the line that passes through (2, -1) and whose y-intercept is 5?
A)2x + y - 5 = 0
B)3x + y - 5 = 0
C)2x + y + 5 = 0
D)3x + y + 5 = 0

2.Write the equation of the line that has a slope of 5/2 and passes through the point (2, 4.5).
A)y = -2.5x + 3
B)2x +5y -1 = 0
C)5x + 2y - 2.5 = 0
D)5x - 2y - 1 = 0

Answer 1

1. Selection B is the only equation satisfied by both (0, 5) and (2, -1).

2. Selection D is the only one with a slope of 5/2.
