y = -8x - 5
y = -8x + 5**
y = 8x - 5
y = 8x + 5

Nope.

-8(2) + 5 = -16 + 5 = -11

y=-8x-5: 4x+17=8x+5 group like terms 17+4x=8x+5 reorder the terms:17+4x=5+8x,17 +4x+8x=5+8x+-8x combine like terms: 4x+-8x=-4x combine thd terms: 8x+-8=0 17+-4x =5+0 17+-4x=5 17+-17+-4x=5+-17 combine like terms 17+-17=0 0+-4x=5+-17 combine the terms 5+-17=-12 -4x=-12 divide each sideby-4 x=3
