Answer
The slope of a line parallel to the given line $2.5$.
Work Step by Step
RECALL:
$\\\\$(i) The slope-intercept form of a line's equation is $y=mx+b$, m=slope and b=y-intercept.
$\\\\$(ii) Parallel lines have slopes that are equal.
$\\\\\\$Write the given equation in slope-intercept form to have:
$\\\\-2y=-5x+6
\\\\y=\dfrac{-5x+6}{-2}
\\\\y=2.5x-3$
$\\\\$The given function has a slope of 2.5.
$\\\\$Parallel lines have the same slopes therefore the slope of a line parallel to the given line also $2.5$.
