Do not round your answers.
y=-2x-21y=−2x−21

Answer 1

I hope you got it right!! :)

Explanation:

Answer 2

• For y-intercept [ x = 0 ]

`{ \rm{y = - 2x - 21}} \\ \\ { \rm{y = ( - 2 * 0) - 21}} \\ \\ { \rm{y = - 21}} \\ \\ { \boxed{ \rm{ \: y - intercept : \: (0, \: - 21) \: }}}`

• For x-intercept [ y = 0 ]

`{ \rm{y = - 2x - 21}} \\ \\ { \rm{0 = - 2x - 21}} \\ \\ { \rm{2x = - 21}} \\ \\ { \rm{x = - 10.5}} \\ \\ { \boxed{ \rm{x -intercept : \: ( - 10.5, \: 0) \: }}}`
