The equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

<h3>Equation of a line</h3>

A line is the shortest distance between two points. The equation of a line in slope-intercept form is expressed as;

y = mx + b

m is the slope

b is the y-intercept

Given that m=1, b=-3, the required equation will be y = x - 3 or x - y = 3

For the parameter m=1, (-1,2)

y - 2 =1(x+1)

y - 2 = x+1

y =x + 3

Hence the equation of the line for the parameters m=1, (-1,2)  is y = x + 3

For the coordinates (-2,3),(-3,4)

Slope = 4-3/-3+2
Slope = -1

For the intercept;

4 =-1(-3) + b

b = 4 - 3

b = 1

Hence the equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

Marianne draws a triangle with the dimensions shown, then she draws a second triangle in which the dimensions are divided by 2.
Dafna11 [192]

Answer:

1/4

Step-by-step explanation:

The equation for the area of a triangle: A = 1/2bh

If all of the dimensions are halved then A = 1/2(1/2*b)(1/2*h) = 1/8bh

1/8bh is 1/4 of 1/2bh.

A ________ indicates how far an individual raw score falls from the mean of a distribution; the ________ indicates how the score
I am Lyosha [343]

Answer:

A <u>z-score</u> indicates how far an individual raw score falls from the mean of a distribution; the <u>standard deviation</u> indicates how the scores in general scatter around the mean.

Step-by-step explanation:

We have been given an incomplete statement. We are supposed to complete the given statement.

We know that z-score of a data set indicates that a sample score or raw score is how many standard deviation away from the mean. Z-score indicates the distance of a raw score is above or below mean in units.

Therefore, the correct word for 1st blank would be "z-score".

We also know that standard deviation represents the variation of a data set. It tells that data points of a data set are how much close or away from mean of the data set.

Therefore, the correct word for 2nd blank would be "standard deviation".
