Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation. If y varies directly as x and as the square of z, and
25
when x - 5 andz -1, find y when x - 1 and z = 4

idk

step-by-step explanation:

use that smart brain

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 for the second equation is (4,0)
