Neither. They can’t be parallel because both lines have different slopes. They aren’t perpendicular either because their slopes don’t multiply to equal -1.
Well you have to make the powers line up so we know r^4 is the highest and you work your way down so
0r^4-5r^3-4r^2-3r
R^4+0r^3-4r^2+3r
So now that they are lined up by power we solve (keep in mind that the 0r's are place holders and have no value)
R^4-5r^3-8r^2
That's your answer
4(y - 1) - 1 = 2(2y - 3)
4(y) - 4(1) - 1 = 2(2y) - 2(3)
4y - 4 - 1 = 4y - 6
4y - 5 = 4y - 6
- 4y - 4y
-5 ≠ -6
What I see is that they are multiplying by 5 so the last one is 10 x 5 which equals 50!
