Answer:

y = -4x -2

Explanation:

lets take two coordinates intersecting the line :

( -1 , 2 ) and ( 0 , -2 )

  • gradient/ slope = ( y1 -y ) / ( x1 -x ) = ( -2 -2 ) / ( 0 - -1 ) = -4 / 1 = -4

now lets find the equation using :

y1 - y = m ( x1 - x )

y - 2 = -4(x - -1 )

y -2 = -4x -4

y = -4x -2
