Answer:
Explanation:
In this specific problem, the only necessary variable to identify is the slope. You can make a table of (x,y) or just choose two points. I chose (2,4) and (4,8). Subtract the y-values and divide it by the difference of the x-values.
y-values: 8 - 4 = 4
x-values: 4 - 2 = 2
4 / 2 = 2
Therefore, the equation is y = 2x.
