Question

Help please i’ve been in here for hours oookung for answers

Answer 1

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 }}}`

Answer 2

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