Write an equation in standard form of the line passing through the points (3,3) and (-3,5)

Korvikt [17]

Answer:

The equation of line AB with points (3,3) and (-3,5) is given as

: x + 3y = 12

Step-by-step explanation:

Here, the given points are A (3, 3) and B (-3,5).

Now, slope of any line is given as :

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

or, $m = \frac{5-3}{-3 - 3} = \frac{2}{-6} = -\frac{1}{3}$

Hence, the slope of the line AB is (-1/3)

Now , A POINT SLOPE FORM of an equation is

(y - y0) = m (x - x0) ; (x0, y0) is any arbitrary point on line.

So, for the point (3,3) the equation of the line is

y - 3 $y-3 = -\frac{1}{3} (x-3) \implies 3y - 9 = 3 -x$

Hence, the equation of line AB with points (3,3) and (-3,5) is given as:

x + 3y = 12

The league championship 800 meter race has 6 runners.

s2008m [1.1K]

Answer: 120

Step-by-step explanation:

Given : The league championship 800 meter race has 6 runners.

The number of positions = 3

Since order matters here , so we use Permutation.

The permutation of n things taking r at a time is given by :-

$^nP_r=\dfrac{n!}{(n-r)!}$

Then, the number of different ways they place first, second, and third :_

$^6P_3=\dfrac{6!}{(6-3)!}=\dfrac{6\times5\times4\times3!}{3!}=120$

Hence, they can place first, second, and third in 120 different ways .

URGENT, PLEASE HELP! (3/5) -50 POINTS- !please no wrong answers for the points.! A) <img src="https://tex.z-dn.net/?f=y%20%3D%20

Answer:

B y = -1/2x + 7/2

Step-by-step explanation:

We know that it has a negative slope since the points go from the top left to the bottom right

We can eliminate A and D

The y intercept is where it crosses the y axis

It should cross somewhere between 2 and 4

C has a y intercept of 9 which is too big

Lets verify with a point

x = -4

y = -4(-4)+9 = 16+9 = 25 (-4,25) not even close to being near the points on the graph

checking B

y = -1/2 (-4) +7/2

= 2 + 7/2 = 11/2 = 5.5 it seems reasonable
