I’ve attached my work....
Perpendicular is when the slope is. Flipped and opposite signs so that’s what I test for each line

It's the last option again. You have 1 linear factor (3<em>x</em>) and 2 copies of a quadratic factor (<em>x</em>² + 10), and the partial fractions with the quadratic factor need to have a linear polynomial in the numerator.
4x+3y=10
You want to isolate the y so subtract 4x from each side
3y=-4x+10
You want to isolate the y so divide everything by 3
y=-(4/3)x+(10/3)
That’s what y is
75.2 is already rounded to the nearest tenth, if you meant tens it's 80
