Question

What is the slope of the line with equation y-3= -1/2(x-2)
(edge 2021)

Answer 1

-1/2

Explanation:

Slope from equation,

y-3= -1/2(x-2)

y-3=-x/2+1

2y-6=-x+2

x+2y=8

m=-coefficient of x/coefficient of y =-1/2=-1/2

Slope from graph,

(2,3), (4,2) as (x1,y1) , (x2,y2)

m=(y2-y1)/(x2-x1)=(2-3)/(4-2)=-1/2
