What's the rate of change of y=4x+7?

2 answers:

8 0

Since this is a linear equation the rate of change or velocity is constant. Take the derivative of y with respect to x...

dy/dx=4

This is commonly called the slope of the line. All lines because they are straight have a constant velocity.

The slope/growth is 4.
Y= 4x+7
Figure 0 / y intercept= 7
The slope / growth = 4

Can someone fr help me with this like right now i’ll appreciate it sm

Step-by-step explanation:

Since

$\frac{108}{72} = \frac{3}{2}$

$\frac{72}{48} = \frac{3}{2}$

$\frac{48}{32} = \frac{3}{2}$

The function has a constant factor so we have a exponential function.

The equation of a exponential function is

$y = a(b) {}^{x}$

Where a is the initial value and b is the growth factor

The growth factor is 3/2,

The initial value in 32

$y = 32 ( \frac{3}{2} ) {}^{x}$

Plug in 4 for x.

You will get 162

Plug in 5 for x you will get

243.
