Question

Graphing functions. -4x + y = -12
Please explain how you got the answer and show your steps using the equation button. Thank you!

Answer 1

solve for y then It will be easy to show how to graph using the y intercept and the slope method

Answer 2

@precal, But I don't know how to solve for y, that's why I submitted the question. >.<

Answer 3

You would ISOLATE 'y' ...so get it by itself on that left side

-4x + y = -12


add 4x to both sides...this way it will cancel out on that left side

-4x + y = -12
+4x +4x

y = 4x - 12

This is a good starting point

From here (slope intercept form) you have the slope, and the y-intercept

y = mx + b
'm' is the slope
'b' is the y-intercept

So when you compare that...to your equation you have

slope = 4
y- intercept = -12

can you graph this from here?

Answer 4

plot (0,-12) from that point you go up 4 and right 1 and plot another point
go back to (0,-12) then you go down 4 and left 1 and plot another point
that plots at least 3 points for you.
