Answer 1

Answer:

B

Step-by-step explanation:

Answer 2

Answer:

(B)As the value of one variable increases, the value of the other variable decreases.

Step-by-step explanation:

Slope is a measure of the steepness of a line. It can be  positive, negative, undefined (vertical),zero (horizontal).

$y=mx+c$,where $m$ is the slope of line.

A line with negative slope slants downward from left to right.

Slope=rise/run=(change in y)/(change in x)

$m=\frac{y_2-y_1}{x_2-x_1}$

When we calculate the slope of downward line then $(y_2-y_1)$ will be negative always so the slope of the line is negative.

However,The slope of line is negative it implies that y always decreases When x increases and y always increases when x decreases.

Hence,As the value of one variable increases, the value of the other variable decreases.
