y - 8 + 2 ≤ -2 + 2  =  y - 8 ≤ -2

Step-by-step explanation:

y - 8 ≤ -2 + 8

Looking at the first couple options we see that the inequality signs aren't the same as the one shown in our given inequality; ≤. Since we didn't do any dividing or multiplying with negative numbers, there should be no reason to change the inequality sign.

This leaves us with the last two equations. However, with the third option, they add 2 to only one side and 8 to one side. It's a known rule that whatever we do to one side of an equation or inequality we must do to the other side. The equation y - 8 + 2 ≤ -2 + 8 doesn't abide by this rule. However, the inequality: y - 8 + 2 ≤ -2 + 2 does.

Both inequalities are equivalent.

y - 8 + 2 ≤ -2 + 2  =  y - 8 ≤ -2

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
