What is the equation of the graphed line written in

Andrew [12]

<u>Given</u>:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

<u>Slope</u>:

The slope of the equation can be determined using the formula,

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

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

$m=\frac{-4-0}{0-2}$

$m=\frac{-4}{-2}$

$m=2$

Thus, the slope of the equation is 2.

<u>y - intercept:</u>

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

$y=mx+b$

Substituting the values, we have;

$y=2x-4$

Subtracting both sides by 2x, we have;

$-2x+y=-4$

Dividing both sides by -1, we get;

$2x-y=4$

Thus, the equation of the line is $2x-y=4$

Hence, Option B is the correct answer.

What is the inverse of f(x)=4x+3 ?

GaryK [48]

<h2>Steps:</h2>

Here are the steps to convert an equation to its inverse:

Change f(x) to y
Switch the positions of x and y
Solve for y
Change y to f^-1(x)

Firstly, do the first two steps:

$x=4y+3$

Next, let's solve for y. Subtract 3 on both sides:

$x-3=4y$

Next, divide both sides by 4:

$\frac{1}{4}x-\frac{3}{4}=y$

<h2>Answer:</h2>

Finally, change y to f^-1(x) and your final answer will be:

$f^{-1}(x)=\frac{1}{4}x-\frac{3}{4}$ , or <u>the second option.</u>

Name a rational and irrational number of 160

nignag [31]

To be pefectly honest, your question really doesn't make sense.
160 is a rational number, and there isn't any irrational number that's
related, connected, or tied to it in any particular way.
