First find the slope of the equation you are given
5x-4y=10
-4y=-5x+10
y=5/4x+10
So your slope is 5/4
Parallel lines have the same slope so the slope of line q is 5/4
Now use the point-slope formula to find the equation
y-(-7)=5/4(x-12)
y+7=5/4x-60/4
y+7=5/4x-15
y=5/4x-8
Line q’s equation is y=5/4x-8
