medal and fan please help me!!!!!!!!!!!!!!!!!!!!!!!!!!

OpenStudy (horsegirl27):

An equation is shown below: 7x + y = 5 Part A: Explain how you will show all of the solutions that satisfy this equation. (4 points) Part B: Determine three different solutions for this equation. (4 points) Part C: Write an equation that can be paired with the given equation in order to form a system of equations that is inconsistent.

OpenStudy (anonymous):

What's the question?

OpenStudy (horsegirl27):

@triciaal can you please help?

OpenStudy (horsegirl27):

I can't exactly do part A, because idk how. And I can't explain something i don't know

OpenStudy (triciaal):

rearrange to get y =

OpenStudy (horsegirl27):

ok

OpenStudy (horsegirl27):

I do -7x on each side then i get y=-7x+5 is that what i need?

OpenStudy (triciaal):

now you have y as a function of x x is the independent variable you control the input x and compute the output y

OpenStudy (triciaal):

part B I think when x = 0 what is y? when y = 0 what is x? when x = y then what?

OpenStudy (horsegirl27):

ok

OpenStudy (triciaal):

part C i don't remember what would be an "inconsistent system"

OpenStudy (horsegirl27):

i remember, want me to say?

OpenStudy (triciaal):

ok

OpenStudy (horsegirl27):

Inconsistent is parallel lines when graphed consistent is overlapping or crossing once

OpenStudy (triciaal):

thank you. parallel lines never meet. have the same slope

OpenStudy (horsegirl27):

ok thanks

OpenStudy (triciaal):

welcome

OpenStudy (horsegirl27):

wait, I'm sorry, but could u explain again part A?

OpenStudy (horsegirl27):

@sleepyjess @Nnesha @triciaal sorry, but I still am kinda confused by how I will show all of the solutions that satisfy the equation.
