The graph of a function must be linear if it has what characteristic? It passes through the origin. It crosses the x-axis more than once.
It crosses the y-axis exactly once
It has a constant slope.

  It has a constant slope.

Step-by-step explanation:

A linear function graphs as a straight line. It will have a constant rate of change.

It has a constant slope.

D. It has a constant slope on Edg2020

Step-by-step explanation:

Hope this helps

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.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
