Answer:

y = 3x - 2

Explanation:

coordinates the given line is passing are ( 0 , -2 ) , ( -6 , -20 )

x1 , y1 x2 , y2

equation to find m, gradient =( y2 - y1 ) / ( x2 - x1)

= ( -20 - -2 ) / ( -6-0 )

= ( -18 ) / ( -6 )

= 3

to find equation,

y - y1 = m( x - x1)

y - - 2 = 3 ( x - 0 )

y + 2 = 3x

y = 3x - 2 is the equation
