Which relation does not represent a function?
(7, 3), (3, 1), (1, 4), (5, 6)
(4, 2), (1, 5), (4, 0), (5, 6)
(2, 0), (4, 8), (6, 5), (10, 5)
(3, 6), (1, 1), (0, 4), (3, 7)
What is the slope and yintercept of the graph of 2x + 3y = 18?
slope = 2; yintercept = (0, 18)
slope = 2 ; yintercept = (0, 6)
 
3
slope = 3 ; yintercept = (0, 2)
 
2
slope = 6; yintercept = (0, 2)

Best ResponseYou've already chosen the best response.1slope is (coefficient of x)/(coefficient of y) and to find the y intercept put x=0 and solve..

Best ResponseYou've already chosen the best response.1B becasue each number represents a domain and range number in a physical plain (4,2) has a Domain of 4 and a range of 2 by laws of math, a real function CAN NOT HAVE THE SAME DOMAIN meaning that if any of the first numbers are the same in the set, it CAN NOT BE A FUNCTION so in B you have (4, 2), (1, 5), (4, 0), (5, 6) since (4,2) and (4,0) both share a 4 as their domain this set can not be a function

Best ResponseYou've already chosen the best response.0For a simpler way to determine if points form a function you plot the points on a coordinate plane (graph the points). Then any time you can draw a lines up and down and if any line goes through more than one point you do not have a function.

Best ResponseYou've already chosen the best response.1well i just explained.. slope is (coefficient of x)/(coefficient of y) = 2/3 and for y intercept put x=0 and you'll get y=6

Best ResponseYou've already chosen the best response.1and if any of the first numbers are the same in the set, it CAN NOT BE A FUNCTION.
