Question 4287: match the terms with the definition:
the term. the definition
y-intercept = 4, contains (-6, -1) A) y = (5/6)x + 4
contains (-1, -6) and slope = 0 B) y = (5/6)x
contains (-6, -8) and (-6, 0) C) y = (-1/4)x
contains (12, 10) and slope 5/6 D) y = -6x - 6
undefined slope and contains (-7, -8) E) y = (-1/4)x - 1
contains (8, -2) and (-4, 1) F) y = -3x
slope -3 and passes through the origin G) x = -7
contains (-1,0) and slope = -6 H) y = -6
contains (4,-2) and m = -1/4 I) x = -6
Passes through (-2,2) and (2, -10) J) y = -3x -4

Question 6077: The instructions were to graph this equation and create a table. This is the solution I came up with, but it is wrong. Where did I make my mistakes?
Problem:
4(x+2)=y+5
4(1)+8=y+5
4+8=12+5 x=1; y=12
4(0)+8=y+5
8=8+5 x=0; y=8
4(2)+8=y+5
8+8=16+5 x=2; y=16
Thank You,
TSJ
