Find an equation of the line that (a) has y-intercept of -6 and (b) is parallel to the line 7x+10y=3\displaystyle -{7}{x}+{10}{y}=-{3}.

Write your answer in the form y=mx+b\displaystyle {y}={m}{x}+{b}.

y=\displaystyle {y}= x+\displaystyle {x}+
 
Write the slope of the final line as an integer or a reduced fraction in the form A/B.
