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
Option B
