Answer:


Step-by-step explanation:

Answer with explanation:

x        -7        -1     3     4       7    

f(x)     -11       1     9    11      17

Slope between two points

     [tex]m=\frac{1-(-11)}{-1+7}\\\\=\frac{9-1}{3-(-1)}\\\\=\frac{11-9}{4-3}\\\\=\frac{17-11}{7-4}\\\\=2[/tex]

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
