Which line has the greatest slope?
y=2/3 x -20
y= 1/3 x +100
y= 2/5 x +2
y= 4/12 x

the first one

Step-by-step explanation:

mx where m is the slope

2/3 > all the others

y = 2/3x - 20

Step-by-step explanation:

The fraction in front of the X determines the slope

y = 2/3x - 20 has a slope of 2/3

y = 1/3x + 100 has a slope of 1/3

y = 2/5x + 2 has a slope of 2/5

y = 4/12x has a slope of 4/12

Y = 2/3 -20 has the biggest slope
