4 5/6 Hope this helps.
You have to find the common denominator for 1/3 & 4/8. & it’s 24. By doing that you have to multiply 3x8, when you do that you also have to multiply 1x 8 so you get 8/24 , same with 4/8 but with three so you get 12/24. Then add your answer 20/24, which equals out to 20/24 which reduces to 5/6. Add 5/6 to 2+2 and you’re left with 4 5/6. Hope this helps.
Negative, because Correlation and slope have the same direction (Sxy will be negative)
The other angel is also equal to x and the sum of all angels need to be 360:
2x+90+26=360
2x=244
X=122
Just put your x to equation and you get y.
Ex.
y = -3(-4)+4
y = 12 + 4 = 16
Sorry I’m not sure but I’ll try and help- lemme just add it to a different comment
