(- 5x^-2y) + (6x^7y^-1)+7x^5

Step-by-step explanation:

Step 1: Write out expression

-5x⁻²y + 6x⁷y⁻¹ + 7x⁵

Step 2: Move negative exponents to denominator

*x⁻² and y⁻¹ have to be moved. Everything else stays.*

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.
