Equation of a line: y=mx+b, m=slope, b=y-intercept
slope=∆y/∆x=(-6-5)/(2+4)=-11/6
Equation:
y=-11x/6+b
solve for b using coordinates from one of given points (-4,5)
5=-11*(-4)/6=b
5=44/6+b
30=44+6b
6b=-14
b=-14/6=-7/3
Equation:: y=-11x/6-7/3

Slope-intercept form shows y as a function of x.
y=mx+b, m is slope and b is y-intercept. Solving for b, you have b=y-mx.
PQ gives slope .
Use the formula for b and pick either given point to compute b.
.......
...and you have/should have all the needed parts for the slope-intercept equation.
