Select all ordered pairs that satisfy the function y = 4x +3.
O (-1-1)
(211)
(4,7)
(71)

(-1,-1 )

and (2,11)

Step-by-step explanation:

put first value to x and second value to y and see if y satisfy the equation

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

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
