Determine whether the relation is a function. {(−3,−6),(−2,−4),(−1,−2),(0,0),(1,2 ),(2,4),(3,6)}

Yes, this is a function

Step-by-step explanation:

This relation is function because 1 x value corresponds to 1 y value

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

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
