Answer:

m=1/4

y=1/4x+2

Step-by-step explanation:

slope is rise over run.  it rises 1 and runs 4

the equation for a liner function is y=mx+b.  Since 1/4 is the slope, replace m with 1/4.  b is the y intercept, and from the graph, you know the y intercept is 2.

In a U. S . Poll 8 out of 12 citizens said they were happy with the job Obama is doing. If 126 people were surveyed...
Solnce55 [7]

8 out of 12 people were happy.

8/12 reduces to 2/3 of the people were happy.

Multiply the total people surveyed by 2/3:

126 x 2/3 = (126 x 2) /3 = 252/3 = 84

84 people were happy.

11. 5x + 5 what does it equal to
Shkiper50 [21]

Answer:

Step-by-step explanation:

Okay this is an odd question, but what i'm thinking is that

first you have

5x+5

To actually be able to solve we have to move the 5 to the other side.

To do this we subtract it.

Making the equation

5x = -5

Then you need to isolate the variable (X)

So divide 5X by 5, and then divide -5/5

Which leaves you with:

x=-1

Una recta con pendiente -2 ´pasa por el punto P(5, -1). La abscisa del punto Q que está en esa recta es 1. Encuentre la ordenada
oksian1 [2.3K]

Answer:

La ordenada de Q es 7.

Step-by-step explanation:

La ecuación de una recta es:

y = a*x + b

donde a es la pendiente y b es la ordenada al origen.

Para este problema, sabemos que la pendiente es -2

Entonces:

a = -2

y = -2*x + b

También sabemos que esta recta pasa por el punto (5, -1)

Esto significa que cuando evaluamos la ecuación en x = 5, y toma el valor y = -1

Si reemplazamos esos valores en la ecuación, obtenemos:

-1 = -2*5 + b

-1 = -10 + b

-1 + 10 = b

9 = b

Entonces la ecuación de la recta es:

y = -2*x + 9

Sabemos que el punto Q está en la línea, y la abscisa de este punto es 1.

Entonces este punto es Q (1, k)

donde k es la ordenada de este punto.

Porque nuestra línea también pasa por este punto, podemos concluir que cuando x = 1, y = k

Reemplazando eso en la ecuación tenemos:

k = -2*1 + 9 = -2 + 9 = 7

k = 7

La ordenada de Q es 7.
