Question

What is the rate of change for y= -3x​

Answer 1

Answer:

• - 3

Step-by-step explanation:

Given line:

• y = -3x

The rate of change is the slope, which is - 3

Answer 2

Answer:

$\frac{y}{x} = m = \tan( \theta) \\ \boxed{y = \tan( \theta) x} \\ \boxed{y = mx}$

where, m and tan∅ is the slope of the line

Here, the rate of change for line y = -3x is the slope of the given line

Comparing the above equation with y = -3x, we get

$\tan( \theta) = - 3 \\ m = - 3 \\ \boxed{\frac{y}{x} = - 3}$

Therefore, -3 is the rate of change for y = -3x

• -3 is the right answer.
