Question

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

Answer 1

Answer:

we know that slope(m)=y2-y1/x2-x1

therefore x1 is 1

x2 is 5

y1 is 3

y2 is 0

m=0-3/5-1

m=-3/4

slope of MN is -3/4

Answer 2

Answer:

slope of MN = -3/4

Step-by-step explanation:

Let say Equation of line containing M & N point is

Y = mX + c

then M is 1 , 3

=> 3 = m(1) + c

=> m + c = 3

=> c = 3 - m

N is (5 , 0)

=> 0 = m5 + c

=> c = - 5m

Equating c from both equations

3 - m = - 5m

=> 4m = - 3

=> m = -3/4

slope of the line = - 3/4

Hence slope of MN = -3/4

or Simiply we can find slope between two point using

(y2 - y1)/(x2 - x1)

M = 1 , 3  N = 5 , 0

slope =  (0 - 3)/(5 - 1)

=> Slope = -3/4

slope of MN = -3/4
