Will give 20 pts and mark brainliest the coordinate grid shows the graph of four equations: a coordinate grid is shown from negative 12 to positive 12 on the x axis and also on the y axis. line a passes through the ordered pairs negative 3, 4 and 9, negative 2. line b passes through the ordered pairs 2, 8 and 8, negative 8. line c passes through the ordered pairs negative 3, negative 4 and 4, 6. line d passes through the points 2, negative 2 and 5 and 6. which set of equations has (5, 0) as its solution? a and b c and d b and d a and d

step-by-step explanation:

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!

constants mean the stopped points or the points on a graph that nothing is changing, hope this
