A line has the points (-3,-8) and (3,y). The slope of the line is 2/3. what is the value of y?

 The value of y is -4.

Step-by-step explanation:

Using the Slope-intercept form formula, we can use the given coordinates for x and y and input it into the formula to solve for the y intercept.  

Slope Intercept formula:  y = mx + b  where m is the slope and b is the y-intercept.

(-3,-8)  Using this point, we will input the values for x and y.

-8 = 2/3(-3) + b

-8 = -2 + b

+2    +2

b = -6  

The y intercept is -6  and the equation will be y= 2/3x -6

Now input the value for x from the point (3,y)and solve for y.

y = 2/3(3)-6

y = 2 -6

y = -4  

This means that when x is 3, the value of y will be -4.

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )
