4 0

Answer:

y=3x-5

Step-by-step explanation:

Slope intercept form is y=mx+b

m represents slope

b represents y-intercept

In the picture, 3 replaces m, so 3 is the slope of the line.

When (2,1) and (5,10) are graphed, the line intercepts -5 on the y axis.

-5 is the y-intercept.

So, (2,1) and (5,10) in slope-intercept form is y=3x-5

max2010maxim [7]

Answer:

5/9

12

Step-by-step explanation:

La clase entera es 1.

1/3 estudian español.

1/9 estudian italiano.

1 - 1/3 - 1/9 estudian alemán.

1 - 1/3 - 1/9 = 9/9 - 3/9 - 1/9 = 5/9

<em>5/9 de los estudiantes estudian alemán.</em>

n = numero total de estudiantes en la clase.

5/9 n = 15

9/5 * 5/9 * n = 15 * 9/5

n = 27

Hay 27 estudiantes en la clase.

27 - 15 = 12

<em>12 estudiantes no estudian alemán.</em>
