Solve for y:
\(\displaystyle{3}{x}-{6}{y}={12}\)
First subtract 3x from both sides:
\(\displaystyle-{6}{y}={12}-{3}{x}\)
Now divide everything by -6:
\(\displaystyle{y}=-\frac{{12}}{{6}}+\frac{{3}}{{6}}{x}\)
Finally simplify:
\(\displaystyle{y}=-{2}+\frac{{1}}{{2}}{x}\)
Then rewrite this as:
\(\displaystyle{y}=\frac{{1}}{{2}}{x}-{2}\)
0

Use what you just learned about negative slopes to solve this problem. A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation y = 200 - 8x can be used to represent this function. Identify the slope and y-intercept and explain what they represent.
