Answer:

The second graph

Step-by-step explanation:

The general function is f(x) = mx + c

  • m is slope
  • c is y-intercept

[tex]{ \tt{m = \frac{8 - 4}{4 - 2} = \frac{4}{2} }} \\ \\ { \underline{ \tt{ \: m = 2 \: }}}[/tex]

For y-intercept:

[tex]{ \tt{f(x) = mx + c}}[/tex]

consider point (2, 4)

[tex]{ \tt{4 = (2 \times 2) + c }} \\ { \tt{c = 0}}[/tex]

Function:

[tex]{ \boxed{ \tt{f(x) = 2x}}}[/tex]
