Question

Help PLEASE!


]Identify the correct x intercept and y intercept of the equation x + 7y = -21.

x intercept = (3, 0); y intercept = (0, 21)

x intercept = (-3, 0); y intercept = (0, -21)

x intercept = (21, 0); y intercept = (0, 3)

x intercept = (-21, 0); y intercept = (0, -3)

Answer 1

y=x/7-3 so y intercept would equal (0,-3)

Answer 2

so wait how did u get tht

Answer 3

oh nvm i see u divided 7 and 21

Answer 4

-21

Answer 5

yupp

Answer 6

so it would be the last one

Answer 7

let me check the x intercept first i just knew the y right off the top of my head

Answer 8

make R.H.S =1 by dividing through out by -21
\[\frac{ x }{-21 }+\frac{ 7y }{-21 }=1\]
\[or \frac{ x }{ -21 }+\frac{ y }{-3 }=1\]
x intercept =-21,y intercept=-3

Answer 9

kool ive never seen it done like that before

Answer 10

i think it would be the lasst one

Answer 11

yupp

Answer 12

it is equation of line in intercept form i.e.,

\[\frac{ x }{ a }+\frac{ y }{ b }=1\]

Answer 13

ok thx @iLuis21 and @surjithayer

Answer 14

no problem

Answer 15
