What is the equation of the horizontal line through (1,9)

Answer:

y = 9

Step-by-step explanation:

To find the equation of a horizontal line through a point, equate the y-coordinate of the point to y.

The y-coordinate is 9. Equate it to y.

y = 9

              y

-------------|-A---------

<u>               |              </u> x

              |

              |

See the Cartesian plane that you graph in. The x-axis and y-axis meet at point (0, 0). Points, or ordered pairs, are written (x, y), which is how far you move left/right on the x-axis, then from there, how far up/down you go.

Horizontal lines go from left to right and are parallel to the x-axis.

The equation of the x-axis is y=0 because it meets the y-axis at 0.

(Pretend) the letter A marks the point (1,9). It moved right one unit, then up 9 units. The horizontal line would hit the y-axis at 9 (and not 0 like the x-axis). Therefore the equation for the horizontal line through (1, 9) is y = 9.

Answer:

slope=9

Step-by-step explanation:

the slope is 9, because you do the y/x or rise over run, so you do for every 9 up 1 right to get a slope of 9/1 or 9

Is 301 in the sequence below?<br> -9, -5,-1,3,7,...
dusya [7]

Answer:

no

Step-by-step explanation:

Establish the nth term formula

There is a common difference d between consecutive terms, that is

d = - 5 - (- 9) = - 1 - (- 5) = 3 - (- 1) = 7 - 3 = 4

This indicates the sequence is arithmetic with nth term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 9 and d = 4 , then

a_{n} = - 9 + 4(n - 1) = - 9 + 4n - 4 = 4n - 13

Equate 4n - 13 to 301

4n - 13 = 301 ( add 13 to both sides )

4n = 314 ( divide both sides by 4 )

n = 78.5

Since n is not an integer then 301 is not in the sequence
