Sixth grade
Because if you divide their total profit by the total amount of hours they worked, you would find that the sixth grade's income per hour is the highest.
Sixth grade: 170÷5=34
Seven grade: 112÷4=28
Eighth grade: 192÷6=32
We know that coordinates are labeled (x,y)
The formula to find slope is (Y2-Y1)/(X2-X1)
So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6
Do the opposite of division which is multiplication. 2.6x2=5.2
I hope I did it correctly and that it benefits you ^^
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
