A slope formula is a number that describes both the direction and the steepness of the line.

The slope formula is attached in the image provided.

The slope formula allows us to find the slope of a line without using its graph. All we need to know are the coordinates of two points that lie on that line.

I'm having trouble in this one, Please help me

mars1129 [50]

Answer:

a. -2/12

b. -0.1

c. 1/9

Step-by-step explanation:

-2/12 = -1/6 < -1/8

-0.1 = -1/10 > -1/8

and 1/9 is the only positive fraction, making it simpler to place.

2.<br> Which of the functions below is an inverse of the quadratic function f(x) = x2 - 3 ?

mezya [45]

Answer:

the inverse of the quadratic function $f(x) = x^2 - 3$ is $\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}$

Step-by-step explanation:

We need to find inverse of the quadratic function $f(x) = x^2 - 3$

Let

$y=x^2-3$

Replace x and y

$x=y^2-3$

Now, we will solve for y

Adding 3 on both sides

$x+3=y^2-3+3$

$x+3=y^2$

Taking square root on both sides

$\sqrt{y^2}=\sqrt{x+3}\\y=\pm \sqrt{x+3}$

Now replace y with $f^{-1}(x)$

$f^{-1}(x)=\pm \sqrt{x+3}$

So, the inverse of the quadratic function $f(x) = x^2 - 3$ is $\mathbf{f^{-1}(x)=\pm \sqrt{x+3}}$

What is the equation of the following line written in general form?

strojnjashka [21]

Eq. of line through (1,2) and (4,5) is
$y-y1= \frac{y2-y1}{x2-x1} (x-x1),
y-2= \frac{5-2}{4-1} (x-1)$ $y-2= \frac{3}{3} (x-1)
y-2=x-1
y-2-x+1=0
y-x-1=0$
x-y+1=0
