Question

Horrible at anything involving graphing. help me figure out the equation? Medal

Answer 1

you need to find two things to write out the equation :
1) y intercept
2) slope

Answer 2

Look at the blue line, where does it cut the vertical axis ?

Answer 3

up five from the point on the left

Answer 4

try again

Answer 5

is that not how to do it? I don't understand what you're asking.

Answer 6

Oh you're finding the slope first is it
then you're right

Answer 7

what about the horizontal distance (run) ?

Answer 8

12

Answer 9

so slope is \(\large \dfrac{5}{12}\)

Answer 10

you could just use the slope formula to find the slope

Answer 11

just find the y intercept and you will be done..

Answer 12

wait and how do i find that?

Answer 13

just eyeball it

Answer 14

oh

Answer 15

its in the middle of 3 and 4?

Answer 16

look at the attached graph, it seems the line is cutting the vertical axis somewhere between 3 and 4 ?

Answer 17

yes! lets say 3.5 ?

Answer 18

write out the equation :
\[\large y = \color{Red}{m}x + \color{red}{b}\]

Answer 19

where

\(\large \color{Red}{m}\) : slope
\(\large \color{Red}{b}\) : y intercept

Answer 20

y=5/12x + 3.5

Answer 21

Excellent!

Answer 22

and thats the final answer?

Answer 23

do you know how to do this one?

Answer 24

@ganeshie8

Answer 25

use the same equation :
\[\large y = \color{Red}{m}x + \color{red}{b}\]

Answer 26

you need to find m and b from the given info

Answer 27

you're given a line, look at it, whats the slope of it ?

Answer 28

the slope is -4/5 ?

Answer 29

Answer 30

hey sry, still here ?

Answer 31

Yeah
