Question

The equation y=ax describes the graph of a line. If the value of A is megative the line:

a) goes down and to the left
b) goes up and to the left
c) is vertical
d) is horizontal

Answer 1

C. It goes up and to the left as y keeps increasing in a positive sense as x keep getting more negative. (and it also goes down and to the right because y keeps decreasing as x increases) and Because, the function will have a negative slope y = -x

Answer 2

go up and to the left
