Step-by-step explanation:
heres a neat trick you can do instead of doing that long process to get 15% of 5321 just use a calculator and do 5321 x .15
X+y=6 is.....
solve for x=0... y=6
solve for y=0... x=6
intersect x-axis at (6,0)... calculate the slop: solve for x=1... 1+y=6... 6-1= 5 y=5
calculate the slope: a= y(x=1)-y(x=0)/1=-1
x+y=6
