Write an equation of the line that passes through the given points. (-1,5) and (2, - 7)

Vanyuwa [196]

Answer:

The equation of the straight line is 4x +y = 1

Step-by-step explanation:

Step(i):-

Given points are (-1,5) and ( 2,-7)

Slope of the line

$m =\frac{y_{2}-y_{1} }{x_{2} -x_{1} } =\frac{-7-5}{2-(-1)} = \frac{-12}{3} = -4$

slope of the line m = -4

Step(ii):-

The equation of the straight line passing through the point (-1,5) and having slope 'm' = -4

$y - y_{1} = m( x-x_{1} )$

y - 5 = -4 ( x-(-1))

y -5 = -4 x -4

4 x + y -5 +4=0

4x +y -1 =0

Final answer:-

The equation of the straight line is 4x +y = 1

Match each term with its notation.

Ugo [173]

Answer:

_k_ The number of treatment conditions

_n_ The number of scores in each treatment.

_N_ The total number of scores in the entire study.

_T_ The sum of the scores for each treatment condition.

_G_ The sum of all of the scores in the research study.

_F_ The F-ratio

Step-by-step explanation:

These notations are ANOVA (Analysis of variance) notations, where

k is the number of treatment conditions

n is the number of scores in the treatment

N is the total number of scores in the entire study

T is the sum of scores for a specific treatment

G is the sum of all scores in the study

and F is the F-ratio.

Now, for the question, we will match each term with its notation

_k_ The number of treatment conditions

_n_ The number of scores in each treatment.

_N_ The total number of scores in the entire study.

_T_ The sum of the scores for each treatment condition.

_G_ The sum of all of the scores in the research study.

_F_ The F-ratio

Someone help me, please!

Valentin [98]

The answer to that is 0. The distance in the y direction is 12 and there are 6 parts 5 before the point and 1 after. So 12/6 = 2 or the length of each part

add 5*2 to -10 = 10 - 10 = 0 that is your answer
