Question

Which graph represents the same relation as the table below? f(x)
–2 5
0 1
1 –1
2 –3

Answer 1

it represents a straight line passing through origin

Answer 2

Answer:

f(x) = 1-2x

Step-by-step explanation:

this is a line

y = mx + c

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

m = (5-1)/(-2-0)

m = 4/-2

m = -2

y = -2x + c

5 = (-2)(-2) + c

c = 1

y = -2x + 1

x = -2. y = 5

x = -1. y = 3

x = 0. y = 1

x = 1. y = -1

x=2. y = -3

f(x) = 1 -2x
