Section 2 - Topic 7 F Solving Linear Systems Using Elimination
1. Consider the following system of linear equations.
1/3x +y= 5/5
2/3x-4/3y=5/3

addition

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
