Suppose y varies directly with x. If y = -4 when x = 8, what is the equation of direct variation?

Pls help me i dont know how to do it
denis-greek [22]
I would start by multiplying both sides of the inequality by 4 to eliminate the fraction

y + 8 >/= 12
Then subtract 8 from both sides
y >/= 4

Because it is greater than OR equal to, when you graph, you use a solid circle. Greater than means the arrow goes to the right on the line.

So, solid circle on the line on 4, arrow pointing to the right. (Third option from the right)
