Question

A line has a slope of Negative three-fifths. Which ordered pairs could be points on a parallel line?

A) (â8, 8) and (2, 2)
B) (â5, â1) and (0, 2)
C) (â3, 6) and (6, â9)
D) (â2, 1) and (3, â2)
E) (0, 2) and (5, 5)

Answer 1

Answer: E

Explanation:

Since parallel lines have equal magnitude of slope.

Recall that,

Slope = (y2 - y1)/(x2 - x1)

Where, y2 is the y-axis for the second point

y1 is the y-axis for the first point

x2 is the x-axis for the second point

x1 is the x-axis for the first point

Therefore, Slope for

(A) 1

(B) -1/5

(C) -1

(D) 1

(E) 3/5

Since the slope of the line is -3/5, therefore (0,2) and (5,5) give a point on a parallel line to it
