Question

•Use the two points on the line and the point-slope formula, y - y1 = m(x - x1), to write the equation of the line.

Answer 1

58,69/61,70

Answer 2

Do you know how to find the slope of the line containing those two points?

Answer 3

yes

Answer 4

Ok, what do you get for that?

Answer 5

y - y1 = m(x - x1 58,69/61,70

Answer 6

The slope of a line containing two points is

m = (y2 - y1) / (x2 - x1)
m = (70 - 69) / ( 61 - 58)
m = 1 / 3

Answer 7

thank u ser

Answer 8

np, know how to finish it?

Answer 9

what can u help with one more

Answer 10

Sure

Answer 11

4.Using the equation that you found in question 2, approximately how tall is a person whose arm span is 66 inches?

Answer 12

Plug the value that @Malaria got for the slope into the point-slope equation for m.
Then pick ONE of the two points you provided. Just ONE. And plug in the respect x and y values into the point-slope equation for x1 and y1.

Answer 13

o ok

Answer 14

respect = respective. keyboard's stuck on slow today.

Answer 15

which point did you pick?

Answer 16

58,69/61,70

Answer 17

which? (58, 69) or (61, 70)? You get to decide which. There is no "wrong" answer in this step of the process.

Answer 18

58,69

Answer 19

Cool. So (58, 69) = (x1, y1). And 1/3 = m.

We'll plug those values into the point-slope form equation.

y - 69 = 1/3(x - 58)

Answer 20

i get it now

Answer 21

Cool.\[y = (1/3)x + (149/3)\]
