Question

Line contains points M(1, 3) and N(5, 0). What is the slope of MN?

a. -4/3
b. -3/4
c. 3/4
d. 4/3

Answer 1

B. Use the formula m=(Y2-Y1)/(X2-X1). For this problem it would be (0-3)/(5-1)= -3/4.

Answer 2

The slope, m, of the line is calculated through the equation,

m = (y₂ - y₁) / (x₂ - x₁)

where x's are the abscissas of the ordered pair and x's are the ordinates. Substituting the given values to the equation above,

m = (0 - 3)/(5 - 1) = -3/4

The slope of the line is -3/4 and the answer is letter B.
