Question

Suppose that y is a linear function of x.
a. Complete the table of values below. (2)
x 0 3 6 ?
y 4 10 ? 24

b. Write a linear equation expressing y in terms of x.
y = ______________________ (3)

Answer 1

lol, can you make the question clear please? :)

Answer 2

the general from of linear function is : y=mx + b
m is the slope, b is a constant
then plug the values of x from the table into the function.
x=0, y=4 -> 4=m(0) +b -> b=4
so now we know the value of b
the function will be -> y=mx + 4
then plug another value of x and y
x=3, y=10 -> 10=3m+4 -> 3m=6 ->m=2

finally we have the complete linear equation : y=2x+4
so when you plug x=6, you'll get y=12+4=16
and when y=24-> 24=2x+6 -> 2x=18 -> x=9

Answer 3

@ sstarica thats what the question looked like onlin haha

Answer 4

@ dindtac how did you get b= 4

Answer 5

by plugging x=0 and y=4 from the table

Answer 6

plug that values of x and y into y=mx + b

Answer 7

yea but then what about m?

Answer 8

oh m times o

Answer 9

plug another values of x and y from the table
x=3 , y=10

Answer 10

yes when you plug x=0 , it will be m times 0 and will left only b in the equation

Answer 11

ok

Answer 12

thanks
