3x-7y=14
Mademuasel [1]

Answer:

A. \frac{3}{7}

Step-by-step explanation:

The given equation is

3x-7y=14

We solve for y by  subtracting 3x from both sides to obtain;

-7y=14-3x

We now divide through by -7 to get;

y=\frac{-3}{-7}x+\frac{14}{-7}

This simplifies to;

y=\frac{3}{7}x-2

This equation is now in the form y=mx +c, where m=\frac{3}{7} is the slope.
