Question

Given the equation 2x+3y=4, how do you answer the following questions?
(a) is the slope of the line described by this equation positive or negative?
(b) As x increases in value, does y increase or decrease?
(c) if x decreases by 2 units, what is the corresponding change in y?

Answer 1

slope = -a/b = -2/3

Answer 2

So, answer b would be decreases since it is a negative?

Answer 3

So, answer b would be decreases since it is a negative?

Answer 4

that is correct
