Alex73 [517]

Answer:

Step-by-step explanation:

x = number of rows

780=x(x+4)

780=x^{2} +4x

x^{2} +4x-780=0\\(x+26)(x-30)=0\\x=30 \\x\neq -26\\

there are 26 rows and 30 students in each row 26*30=780

luda_lava [24]

Answer:

Step-by-step explanation:

y=mx+b where m=slope and b=y intercept

m=(y2-y1)/(x2-x1), we have points (0,0) and (4,12)

m=(12-0)/(4-0)=12/4=3

y=3x+b, using point (4,12) we can solve for b

12=3(4)+b

12=12+b

b=0 so the line is

y=3x
