Answer two questions about Systems A and B: System A
{-10x-4y=0
{-2x+7y=8

System B
{-10x-4y=8
{-2x+7y=0

1) How can we get System B from A?

Choose 1

A) Replace only the left-hand side of one equation with the sum/difference of the left-hand side of both equations.

B) replace one equation with the sum/difference of both equations.

C) Swap only the right-hand side of both equations.

D) Swap the order of the equations

2) Based on the previous answer, are the systems equivalent? In other words, do they have the same solution?

A) yes
B) no

the correct answer is 1: 2

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
