Two Points are: (2,4) and (6,16).
What is the slope? (Number)

What is the y-intercept? (Number)

Write a linear equation y=mx + b to represent the table:

1. m=3

2. b= -2

3. Y=3x-2

Step-by-step explanation:

slope= m

M

m=

(16-4)/(6-2)= 12/4 = 3

m=3

Y-intercept =b

So by substituting any of the coordinate into y=mx+b we get.

4=3(2)+b

4-6=b

-2=b

b= -2

Linear equationy=mx+b becomes :

Y=3x-2

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
