Question

Graph the function f(x)=−1/4x−2. Use the line tool and select two points to graph

Answer 1

Answer:

The given function is

$f(x)=-\frac{1}{4}x-2$

Notice that this function is linear, that means its graph is a straight line.

To graph a linear funtion you just need to use two coordinates.

For $x=0$

$f(0)=-\frac{1}{4}(0)-2=-2$

For $y=0$

$0=-\frac{1}{4}x-2\\ 2=-\frac{1}{4}x\\x=-8$

So, the points you need are $(0,-2)$ and $(-8,0)$.

The image attached shows the graph of the given function, where you can observe the two ponints we used.
