16 students in 2 rows
8 students in 4 rows
4 students in 8 rows
2 students in 16 rows
1) we find out the equation of the line
point-slope form; we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀)
In this case:
point: (4,5)
slope: 6
Therefore:
y-5=6(x-4)
y-5=6x-24
y=6x-24+5
y=6x-19 (slope-intercepted form)
2)we find out "y" when x=24
if x=24; then
y=6(24)-19=144-19=125
Answer: y=125
Answer:
x=-4/3
Step-by-step explanation:
3x-12=12x
3x-12x=12
-9/-3=12/-3
then -3 cancels
3x/3=-4/3
then 3 cancels 3
so x=-4/3
