HELP ASAP EASY MATH Line $a$ is parallel to line $b$ and goes through the point $(1,2)$. Line $b$ goes through the point $(3,1)$ and is perpendicular to line $c$ whose equation is $y=-2x+3$. Find the y-intercept of line $a$.

-22/3

Step-by-step explanation:

I'm assuming you want the improper fraction of -7 1/3.

Multiply the denominator of 1/3 (which is 3) by -7, which should give you -21. Add the remaining of the numerator of the fraction, (which is 1) to get -22. Put that over 3, and you get -22/3.

here's the work:

-7 1/3

= -(21+(-1))/3

=-22/3
