Question

Choose the correct graph of the given system of equations.

y − 2x = −1
x + 3y = 4
A graph of two lines, one with a positive slope and one with a negative slope, that intersect
at the point (negative 1, 1)

B graph of two lines that intersect at the point (1, 1)

C graph of two parallel lines with positive slopes

D None of the above

Answer 1

Answer 2

do you know how to solve for x and y ??

Answer 3

um I am kinda confused on that

Answer 4

alright there are two options
graph both equations

or solve both equations for y to find slope

Answer 5

to find slope you have to rewrite the equation in slope intercept form
y=mx+b
so
y − 2x = −1
can you solve this equation for y ?

Answer 6

um so you would isolate 2x right?

Answer 7

how would you do that ?
would add ,subtract,divide or multiply both sides by 2x ?

Answer 8

divide would be opposite so multiply by 2x

Answer 9

isolate 2x means you're solving for 2x
isolate y
and it's `-2x` y is subtracted by 2x what's opposite of subtraction

Answer 10

sorry my chair was holding down the enter button

Answer 11

addition

Answer 12

right add 2x both sides
