Use the information given to write an equation in standard form. Slope is -2, and (4, 3) is on the line.

Step-by-step explanation:

Standard form of an equation is written as for some constants , , and .

Slope-intercept form is written as where is the slope and is the y-intercept.

Plugging in all given values in the problem (, , and ), we can solve for :

.

Therefore, our equation in slope-intercept form is:

.

Rewriting in this in standard form, we get our

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!
