Answer:

f(x) = 3.33x - 7

Explanation:

We are suppposed to write the slope intercept form of the line . The slope intercept form of the line is ,


\rm\implies y = mx + c

where ,

  • m is slope
  • c is y intercept .

Here we can see that the line is passing through (0,-7) . Therefore ,


\rm\implies y- intercept = -7

Also we can see that the line is passing through (2.1,0) . Therefore we can find the slope as ,


\rm\implies Slope =(y_2-y_1)/(x_2-x_1)\\\\\rm\implies Slope =( -7-0)/(0-2.1)\\\\\rm\implies \bf Slope = 3.33

Using Slope Intercept Form :-


\rm\implies y = mx + c \\\\\rm\implies y = 3.33x + (-7) \\\\\rm\implies\underline{\boxed{\rm\blue{f(x) = 3.33x - 7 }}}

F(x) = 3x - 7 is the correct slope-intercept form.
