Solve this system of equations.
2x + 2y + 7z = -1
2x + y + 2z = 2
4x + 6y +z = 15

x =1

y = 2

z = -1

Step-by-step explanation:

I Hope it helps. Please if you need any clarification, let me know .

ummm seems that u didnt post the attachement !

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
