Using the substitution method, Vito is solving the following system of equations algebraically. Which equivalent equation could Vito use? y=-3x-4
2x-3y=-21

A. 2(-3-4)+3x=-21
B. 2x-3(-3x-4)=-21
C. 2(3x-4)+3x=-21
D. 2x-3(3x-4)=-21

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.

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

idk lol xd
