Answer 1

f ind slope of the curve = rise / run = (16-12) / (32 - 20) ( picking the points around
the point (32,16)

the taking the point (32,16) as (x1,y1) substitute for m ( the slope) in the general form

y - y1 = m(x - x1) and simplify

slope = m = about 4/12 = 1/3

Answer 2

yes i know how to do that part but isn't there another part

Answer 3

you just plug in x1 = 32 y1 = 16 into the above and simplify to get one of the choices .

Answer 4

oh I didnt use the 2 data points closest to the line but the slope i got was the same

they wanted you to use the points (32,16) and (26 ,14) which gives you the same slope
16-14 ) / 32 - 26 = 2/6 = 1/3

Answer 5

i know the part of 1/3 i dont what the rest

Answer 6

y - 16 = (1/3) )x - 32)

Answer 7

first multiply both sides by 3
3y - 48 = x - 32

Answer 8

y-16=1/3x-32
+16 +16
y=1/3x-16/32

Answer 9

No theres an error in the first line
the 1/3 multiplies everything in the brackets it s

y - 16 = 1/3 ( x - 32)

Answer 10

y - 16 = (1/3) x - 32/3

Answer 11

i really dont get i just stuck can you work it out so i can understand it

Answer 12

ok lets go back

y = y1 = m(x - x1) is the slope /point form of the equation of the line

m = slope = 1/3 and we take the point x1 = 32 and y = 16 and plug these in

y - 16 = (1/3) ( x - 32)

OK so far?

Answer 13

yea

Answer 14

ok

now theres a few ways we can proceed from here
I dont like messing with fractions much so if we multiply both sides of the equation by 3 , the 1/3 on right side of the equation disappears
So multiplying both sides by 3:-

3y - 48 = (x - 32)

and we can drop the brackets

3y - 48 = x - 32

Answer 15

okay

Answer 16

3y - 48 = x - 32
+48 + 48

3y = x + 16

dividing through by 3


y = (1/3)x + 16/3

Answer 17

sorry guy i have to go right now

Answer 18

hope this helped

Answer 19

i'm back
