Step-by-step explanation:

First get x on its own:

 

Subtract 3 from each side

y - 3 = 2x

 

Divide through by 2

y/2 - 3/2 = x

or x = y/2 - 3/2

 

Now simply switch labels: x↔y

y = x/2 - 3/2

Answer:

y=\frac{x}{2}+\frac{3}{2}

Step-by-step explanation:

To find inverse of an equation, replace the variables x with y and y with x:

x = 2y - 3

Now we get it in slope-intercept form:

x = 2y - 3

Add 3 to both sides.

x + 3 = 2y

Divide both sides by 2.

\frac{x}{2}+\frac{3}{2}=y

Swap left and right sides.

y=\frac{x}{2}+\frac{3}{2}

And this is the inverse of the equation y = 2x - 3.

I hope you find my answer helpful.

What is the equation of the circle shown in the graph
schepotkina [342]
The general equation for a circle is:
(x-h)^2 + (y-k)^2 = r^2

where (h,k) is center of circle
r = radius

For this example, from the graph you see the center is at (0,-3) and radius is 2.
h  = 0, k = -3, r = 2

Sub into general equation:
(x-0)^2 + (y-(-3))^2 = 2^2 \\  \\ x^2 +(y+3)^2 = 4
