Question

@borak

Answer 1

this is adavanced one :D from the previous

Answer 2

yeah xD

Answer 3

first of all formula of the linear function :-
y -y1 = m(x-x1) ; /the point (x,1y1) is the line or in the function

Answer 4

could choose any point please ?

Answer 5

5,0 and 0,4

Answer 6

this wise choose because made the calculation more easy;
let's find the slope

Answer 7

(5,0) and (0,4) cout you please find slope ?

Answer 8

(y1-y2)/(x1-x2) = slope of function

Answer 9

5/4?

Answer 10

your equation can be written in segmentary for, namely:
\[\frac{ y }{ 4 }+\frac{ x }{ -5 }=1\]
from whic, we have:
\[5y=4x+20\]
then:
\[y=\frac{ 4 }{ 5 }x+4\]

Answer 11

no ,opposite 4/5

Answer 12

the y up and the x down

Answer 13

5/4

Answer 14

is the answer y=0.8x+4?

Answer 15

@gummybear1021 yes, it is!

Answer 16

yes

Answer 17

if in my answer I set y=0, then I have:
\[0=\frac{ 4 }{ 5 }x+4\]
and then:
\[x=-5\]
as we can see from the graph

Answer 18

(4/5) the slope

Answer 19

can i tag you guys both in another question?

Answer 20

yes!

Answer 21

yes
