Find equation of line first

  • (2,8)
  • (4,16)

Slope:-

[tex]\\ \tt\hookrightarrow m=\dfrac{16-8}{4-2}=\dfrac{8}{2}=4[/tex]

Equation in point slope form

[tex]\\ \tt\hookrightarrow y-8=4(x-2)[/tex]

[tex]\\ \tt\hookrightarrow y-8=4x-8[/tex]

[tex]\\ \tt\hookrightarrow y=4x[/tex]

  • pUt y=16

[tex]\\ \tt\hookrightarrow 16=4x\implies x=4[/tex]
