Mor math help?

1 Find the slope and y-intercept for the graph of the equation: 4x - 2y = 24





2 Find the slope and y-intercept for the graph of the equation: 12x - 4y = 96.





3 Find the slope and y-intercept for the graph of the equation: 9x - 3y = 81.





4 For banquets, Flourishing Flowers charges $60 for each standard floral arrangement plus a one time $125 fee for delivery and set up. Write an equation in slope-intercept form that shows the cost y for flowers for x number of arrangements.


1 x = 60y + 125


2 y = 60x + 125


3 y = 125x + 60


4 x = 125y + 60

The equation to find slope and the y-intercept is y=mx+b where m is the slope and b is the y-intercept.





4x - 2y = 24


-2y = -4x + 24


y = 2x - 12


m= 2


y-intercept = -12





12x - 4y = 96


-4y = -12x + 96


y = 3x - 24


m= 3


y-intercept = -24





9x - 3y = 81


-3y = -9x + 81


y = 3x - 27


m = 3


y-intercept = -27





flowers: $60x


one time fee: $125


y = $60x + $125
Reply:The equation for finding the slope and y-intercept is:





y = mx + b





where m is the slope


and b is the y-intercept.





Put your problems in this form and you will be able to determine the slope and y-intercept.
