Answer:

D) When x=2, y=14
When x=4, y=28

Step-by-step explanation:

By using slope= y2-y1/x2-x1

I get (1,7) and (3,21) from the table

slope= 21-7/3-1= 14/2= 7

Then I plug in the values into y=mx+b

7= 7(1) +b

b= 0

Getting an equation of y=7x

When x= 2

y= 7(2)= 14

When x= 4

y= 7(4)= 28

48 girls, 41 boys, and 5 teachers sat in the gym. Write the ratio of girls to boys in three ways.

Anika [276]

Answer:

Step-by-step explanation:

The answer is D because the question is asking for girls to boys. So anything that has 5 in it is wrong because it isn't asking for teachers, which eliminates A. So since it is asking girls to boys the number order has to be 48 then 41 because it is asking for girls first then to boys. So that makes B wrong. When it comes to the fraction part of the ratio the first number it is asking for (which is girls) always goes on top. So that eliminates C which leaves only answer to be D.
