Question

Solve the system 2x + 3y = 3 and 3x – 2y = 11 by using graph paper or graphing technology. What is the solution to the system?

(–3, 3)

(–1, –7)

(1, –4)

(3, –1)

Answer 1

you can try by substituting the points on the equations to see which one is true
example, lets take point (-3,3)

2x + 3y = 3
2(-3) + 3(3) = 3
-6 + 9 = 3
3 = 3 ok

then

3x - 2y = 11
3(-3) - 2(3) = 11
-9 -6 = 11
-15 = 11 NOT TRUE, so this point won't satisfy both equations not good

Answer 2

or you can graph the equations, and see where they meet.
example 2x + 3y = 3

3y = -2x + 3
y = -3/2x + 1

Answer 3

so you would do the substitution method with the answer choices until they are both true?

Answer 4

correct

Answer 5

ok then thanks
