So the y intercept is 6, then because of the 2 slope you go 2 points up and 1 to the right

Hello!

The given function is a line, to graph it, we need to find the axis intercepts using all the information we have.

So,


f(x)=2(x+3)=2x+6

Where:


slope=VariableCoefficient=2\\YAxisIntercept=Constant=6\\XAxistIntercept=-3

Since it's a possitive slope, the function is increasing.

We cand fint the x-intercept by making the function tend to zero (0), so:


0=2x+6


-6=2x


x=(-6)/(2)=-3

We can find the y-intercept by making the variable tend to zero (0), so:


f(0)=2(0)+6


y=6

Therefore, the intercept points will be (-3,0) and (0,6)

For the graph, see the attached image.

Have a nice day!
