Answer:
3 is the gradient.
Explanation:
take coordinates through which the line is passing through like
( 0 , -2 ) and ( 6 , 16 )
to find slope/ gradient = ( y2 - y1 )/ ( x2 -x1 )
= ( 16 - -2 ) / ( 6 - 0 )
= 3
to confirm, let me find the equation as well:
y - 16 = 3 ( x - 6 )
y - 16 = 3x - 18
y = 3x - 2
below for visual check. its true and matches. { confirmed }
