Answer: y= 3x - $6\frac{1}{2}$

Step-by-step explanation:

Since we know the slope and a set of coordinates we can insert them into the formula y=mx+b and find what b is.

y=mx+b

-1/2=3(2)+b

-1/2=6+b

-1/2-6=6-6+b

-6 1/2=b

Therefore the equation is y=3x - $6\frac{1}{2}$

Which equation can pair with 3x + 4y = 8 to create a consistent and independent system?

Hunter-Best [27]

There isn't any choices given in this problem but I can give you a tip to answer these kinds of problem. When you say independent, it means that the equation cannot be algebraically altered to result to 3x + 4y = 8. So the equation 6x + 8y = 16 is not an independent equation since when you divide each side by 2 it will result to 3x + 4y =8. You get the idea. <span />
