4x - y = 7 I need ordered pairs for this linear equation, I was wondering of some possible solutions. Thanks!

Uhh im not sure if this is right but i think you should first put it in slope intercept form.

then make an X and Y chart to find solutions.

y=4x-7

(0,-7)
(1, -3)
(2, 1)

Would (2,1) (3,5) and (4,9) work as well? Thanks!

• Algebra -

yea i got (2,1) in my first post. Yeah, they should all work.

• Algebra -

Even though you switched it to the y = 4x - 7? Is this all the same or is the -7 and 7 the constants changed? Thanks

• Algebra -

no, when i put in slope intercept form i got -7

the original equation was
4x-y=7
subtract 4x to both sides
-y=-4x+7
you cant have a -y so move the negative over, this will change the sign of everything

y=4x-7

• Algebra -

then the slope intercept form of that would be

y=-4x+7

• Algebra -

So which is the correct method? Switching the original, or just using variables as i did to make the equation true

4x-y = 7

4(2) - 1 = 7 (2,1)

4(3) - 5 = 7 (3,5)

4(4) - 9 = 7 (4,9)

Which method is correct? Or does it not matter because the equation has infinate solutions? Thanks!

• Algebra -

Both method is fine.

Are you a math teacher? Just wondering?

• Algebra -

no im not. but im in alg 2

• Algebra -

That makes sense..High School?

• Algebra -

yeah high school.

Ok! Have a good night and thanks for the help!
