Same
Nnesha (nnesha):
positive number is bigger than negative number
or negative number is bigger then positive???
OpenStudy (triciaal):
put each equation in the same format
y = mx + c
rate of change is the slope is m
the higher the number the higher the rate
Nnesha (nnesha):
what is slope of the equation B ??
OpenStudy (dan815):
take derivative

or find slopes
Nnesha (nnesha):
GREATEST RATE OF CHANGE
OpenStudy (anonymous):
I don't get B
Nnesha (nnesha):
Y = 7x - 8 they already solved this for u
y = mx + b where m is slope
OpenStudy (anonymous):
oh so B

so for A the slope is 2
for B the slope is 7
for C the slope is -15/5 =
for d the slope is ? it looks like 6/2
put all the numbers in order which is the highest?
