Step-by-step explanation:
slope-intercept form:

Start with the given equation, and to find the slope, convert it to slope-intercept form by solving for y.

In this case, all you need to do is subtract 3x from both sides.

Here, the slope is -3. The slope of a parallel line will also be -3.
Now, we have 3 known variables. We have the slope and the x and y of a known point. Use those 3 knowns to solve for the 1 unknown, the y-intercept.

Finally, with the slope and the y-intercept, you can write the equation of the line:

Answer:
14
Step-by-step explanation:
mass of 100 centimeters of copper wire is 
so, mass of 1 centimeter of copper wire will be 
hence, 14 centimeters of copper wire will provide .28 copper
18 inches.
12/4=3 so you would multiply 6•3 to get 18
