Answer:
Graph y = 2x
Step-by-step explanation:
First, let's get the equation into standard form. Distribute the 2 on the right.
[tex]y-4=2x-4[/tex]
Next, we want the variable "y" to be alone, so we at 4 to both sides.
[tex]y-4+(4)=2x-4+(4)\\\\y=2x[/tex]
That is our equation in standard y = mx + b form. "m" is our slope, while "b" is our y-intercept. Above , we don't have a value for b, therefore the line passes through the origin.
We do, however, have a slope, which can be thought of as [tex]\frac{rise}{run}[/tex] or rise over run. To represent this, we can rewrite our slope as:
[tex]y=\frac{2}{1}x[/tex]
Meaning in each interval, the line goes up by 2 units, and moves forward by 1.
