Question

Given that f is a linear function for which f(-3) = 0 and f(3) = 6
determine f(0)=?

Answer 1

can you write the equation of a line that passes through the points
(-3, 0) and (3,6)?

Answer 2

?

Answer 3

this is what the question is asking you to do

Answer 4

oh ok i didnt understand that

Answer 5

its only asking for a single number

Answer 6

when you write the equation of this line, plug in 0 for x and you will get your y-coordinate

Answer 7

yes, but in order to get this number, you must write a linear function that relates the first two values

Answer 8

ok i see

Answer 9

so doing y1-y2/x1-x2 I will get the cord. and the answer

Answer 10

you will get the slope of the line

Answer 11

so making it short 6/6?

Answer 12

yes, now you have the slope

Answer 13

to get the equation of the line, you need to find the y-intercept

Answer 14

the y-intercept is the answer to your question in this case

Answer 15

so then I do y-y1=m(x-x1)

Answer 16

right

Answer 17

ok and "M" being the 6/6 right?

Answer 18

yes, you can use 1 for m because 6/6=1

Answer 19

so would x be the 0 or x1?

Answer 20

never mind I got it
