Equations

Are these two lines parallel, perpendicular, the same line, or none of these?

$$−3x=3y+6$$
$$4x+4y=2$$
a) perpendicular
b) the same line
c) parallel
d) none of these

Write each line in slope-intercept form $$y=mx+b$$ by solving for y.
$$\displaystyle−{3}{x}−{3}{y}+{6}→{y}=−{x}−{2}$$
$$\displaystyle{4}{x}+{4}{y}={2}→{y}=−{x}+\frac{{1}}{{2}}$$
