problem

Line aa is parallel to line bb and goes through the point (1,2)(1,2). Line bb goes through the point (3,1)(3,1) and is perpendicular to line cc whose equation is y=−2x+3y=-2x+3. Find the y-intercept of line aa.
Plain-text mathematical notation (without MathML)
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.
Original LaTeX notation
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 $a$.
