Video Solution

Solution Steps

00:00 What is the rate of change of the function?
00:02 The rate of change of the function is the slope of the function (X coefficient)
00:05 And this is the solution to the question

Step-by-Step Solution

To solve this problem, we need to determine the rate of change of the linear equation given by:

y=4x+3 y = -4x + 3

The standard form for a linear equation is:

y=mx+b y = mx + b

where m m represents the slope of the line. The slope indicates the rate of change of the function, which describes how much the value of y y changes for a unit change in x x .

In the equation y=4x+3 y = -4x + 3 , the slope m m is 4-4. This means that for every unit increase in x x , the value of y y decreases by 4. Thus, the rate of change for this equation is 4-4.

Therefore, the rate of change is 4 -4 .

Answer

4 -4
