How to find the slope from a table of data

sammy [17]

The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is $\frac{dy}{dx}$ or:

$\frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

Example:

Let's say you're give this table:

x: 1, 2

y: 1, 2

Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1

Do the same for x

Now plug the values taken in the slope formula and you get:

$\frac{2 - 1}{2 - 1}$

$\frac{1}{1} = 1$

Therefore the slope is 1.

HELP WILL MARK BRAINLIEST!!!

Rainbow [258]

Answer:

Let's see what to do buddy..

Step-by-step explanation:

_________________________________

STEP (1)

We know that the quadratic functions form are like this :

$y = a \: {x}^{2} + b \: x + c$

The quadratic function opens upward so ;

$a > 0$

The axis of parabolic symmetry passes through the vertex of the parabolic.

So we know that x vertex is equal to -2.

The vertex's x is finding from this equation:

$x = - \frac{b}{2a} \\$

So we have :

$- 2 = - \frac{b}{2a} \\$

Multiply the sides of the equation by <em>2</em><em>a</em> :

$b = 4a$

_________________________________

STEP (2)

A quota passes through points (-3,2) and (0,11) , so points (-3,2) and (0,11) must be true in the quota equation.

$y = f(x) = a{x}^{2} + bx + c \\ \\b = 4a \\ \\ y = f(x) = a {x}^{2} + 4ax + c$

$f( - 3) = 2 \\ \\ a ({ - 3})^{2} + 4a( - 3) + c = 2 \\ \\ 9a - 12a + c = 2 \\ \\ - 3a + c = 2 \\ \\ \\ \\ f(0) = 11 \\ \\ a ({0})^{2} + 4a(0) + c = 11 \\ \\ c = 11$

$- 3a + c = 2 \\ \\ c = 11 \\ \\ - 3a + 11 = 2 \\ 11 \: goes \: to \: the \: other \: side \: \\ \\ - 3a = 2 - 11 \\ - 3a = - 9 \\ divided \: the \: sides \: of \: the \: equation \: by \: - 3 \\ a = 3$

And we're done.

Thanks for watching buddy good luck.

Matt has more than 41 marbles and fewer than 43 marbles.Maya Has More than 47 marbles and fewer than 49 marbles

AnnZ [28]

Answer: Matt has 42 marbles and Maya has 48 marbles.

Step-by-step explanation:

Matt's has more than 41, but less than 43 marbles. Since each marble has to correspond to a whole and real number, the only number between 41 and 43 is 42. Likewise the only number between 47 and 49 is 48 since Maya has more than 47 marbles but less than 49 marbles.

The length of a rectangle is 3 units more than the width. The area of the rectangle is

Anastaziya [24]

Answer:

8 units for the length

Step-by-step explanation:

Let l = length

w = width

l = w+3

A = l*w

substitute what we know

40 = (w+3) *w

distribute

40 = w^2 +3w

Subtract 40 from each side

0 = w^2 +3w -40

Factor

0 = (w+8) (w-5)

Using the zero product property

w+8 =0 w-5=0

w= -8 w=5

Since the width cannot be negative

w=5

l = w+3 = 5+3

l = 8 units
