Atrinomial that contains the variable k the coefficient of the second degree term is 1, the coefficient of the first degree term is -7 and the constant term is -15 how would you write this?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

not sure but it may be b, as i said i'm not sure.
