16-5y=1-4y

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:

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

14 x 10 5

step-by-step explanation:

10 5 = 100,000

14x10,000 = 140,000
