Which is not equivalent to -2+9a -4+ -3b -1× -7c 10+ -3d -3- -10

A. is the answer

-2 + 9 is 7, and A. -4 + -3 = -7.

- 2 +9 = 7

a.  -3 + -4  = - 7

b, c and d = 7

So the answer is  a

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
