Question

Find the slope of each line.

Line A: (6,4) & (-3,-1)

Line B: (-6,0) & (3,5)


a) line a= 5/9 line b= 5/9

b) line a= 9/5 line b= 9/5

c) line a= -5/9 line b= -5/9

d) line a= -9/5 line b= -9/5

Answer 1

a) line a= 5/9 line b= 5/9

Explanation:

Use the slope formula:

m = y2 - y1

x2 - x1

Plug-in the known values for each line:

Line A: -1 - 4 = -5 = 5

-3 - 6 -9 9

Line B: 5 - 0 = 5

3 - (-6) = 9
