Question

Identify the slope of the line through points (3,4) and (-4,-5).

a. -9/7
c. 0
b. -1
d. 9/7
A
D
B
C

Answer 1

b) D => d. 9/7

Explanation:

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (-5 - 4)/(-4 - 3)

→ m = (-9)/(-7)

→ [ m = 9/7 ]

Hence, the slope is 9/7.
