–1

1

3

9

4

11

7

17

a f(x) = 3x + 10

b f(x) = 2x + 3

c f(x) = 4x + 5

d f(x) = 3x – 10

Answer 1

Explanation:

Answer 2

Answer with explanation:

x -7 -1 3 4 7

f(x) -11 1 9 11 17

Slope between two points

`m=(1-(-11))/(-1+7)\\\\=(9-1)/(3-(-1))\\\\=(11-9)/(4-3)\\\\=(17-11)/(7-4)\\\\=2`

Equation of line will be

⇒y-(-11)=2×[x-(-7)]

→y+11=2×(x+7)

→y+11=2x+14

→2x-y+14-11=0

→2x-y+3=0

→y=2x+3

Option B
