I'm unsure how to solve this... can someone help me?
Match the equation with its graph.
−6/7 x - 1/2 y = 3/7
The answers are graphs, so I'll type the coordinates of the graphs here.
A.) -1, 4; -6, 4
B.) -1, -4; 4, 6
C.)-4, -6; 4, 8
D.) -4, 6; 2, -4

are you from connections Abigail?
first of all let's clean up the equation
multiply each term by 14 , the LCD
-12x - 7y = 6 , or even nicer..
12x + 7y = -6
slope = -12/7 , which leans to the left
ruling out A, B, and C.
A is horizontal and B and C have positive slopes
this leaves D
I will leave it up to you to test if (-4,6) and (2,-4) satisfy my simplified equation
