Question

Mark thinks the equation y= 4+6x will match the red solid graph. Mia thinks it will match the blue dotted graph. Who’s right? Mark. Or. Mia

Answer 1

Given:

The given equation is

$y=4+6x$

Solution:

Now, for x=0 we have

$y=4+6(0)=4$

And, for y=0 we have

$\begin{gathered} 0=4+6x \\ x=\frac{-4}{6}=\frac{-2}{3} \end{gathered}$

which shows that the vlue dotted graph is the correct graph of the equation.
