Answer:

y=2x+3

Step-by-step explanation:

the general form of a line is:

y=mx+b

where m is the slope, and b is the point where the line crosses the y-axis.

From the graph we can see that said line crosses the y-axis at

+3

the the b in our solution must be+3 , we willl have a result of the form:

y=mx+3

That rules out options A and C

Now to calculate the slope we take two points where the graph passes, I will take the points:

(-2,-1)and (0,3)

tag the coordinates

x_{1}=-2\\y_{1}=-1\\x_{2}=0\\y_{2}=3

and use the slope equation

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

substituting the values:

m=\frac{3-(-1)}{0-(-2)} \\m=\frac{3+1}{2}\\ m=\frac{4}{2} \\m=2

the slope of the line is 2, so the equation of the line is:

y=2x+3

which is option B

Counting the number of times a third-grade student leaves his seat without permission during a 30-minute observation period is a
notka56 [123]

Answer:

Behavioral modality of measurement

Step-by-step explanation:

Observing a 3rd grade student for 30 minutes as to how many time he leaves his seat without permission is a clear example of using behavioral modality of measurement.

In this modality of measurement the behavior of the object or system is observed when it is put into action.

This example shows as to what will happen or what is supposed to take place when a 3rd grade student is is seated and observed for 30 minutes. It counts as to how many times he leaves his seat in reaction to his stimulus from the environment.

[ please help! ] The graph below shows a line segment PQ.
Tpy6a [65]

Answer:

Slope of the line segment PQ is 1/2.

Step-by-step explanation:

We are given with a line connecting two points P and Q.

The coordinates of P are (4,4) and the coordinates of Q are (-2,1).

Slope of line joining two points (x_{1},y_{1}) and (x_{2},y_{2})

is given by the formula \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Hence the slope of the line PQ is \frac{1-4}{-2-4}=\frac{-3}{-6}= \frac{1}{2}

Therefore correct option is 'C' that is 1/2.

How would you write the equation with a slope of 2/3 and a y-intercept of -3 in slope- intercept form
Alexxandr [17]

y=2/3x-2

Explanation:

The equation of a line can be written as y=mx+c

m=slope and c = y-intercept

The point at the x−intercept has coordinates (-3,0)

In y=mx+c

0=2/3(3)+c

0=2+c

-2=c

The equation is y=2/3x-2
