Question

What is the slope of the line that passes through the points (4, -6) and (-5, 9)?

-5/3
-3/5
1/3
5/3

Answer 1

Explanation:

(4, -6) and (-5, 9)

Slope is m

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

y2 = 9, y1 = -6, x2 = -5 and x1 = 4

m = {9-(-6)}/{-5 -4}

m = {9+6}/(-9)

m = 15/-9

m = -5/3

Answer 2

-5/3

Explanation:

gradient/m = y1 - y2/ x1 - x2

so, 9-(-6)/ -5-4

= 15/-9 , which simplifies to -5/3 If divided both numbers by 3
