Answer:
m = -3
b = 0
equation of line
y = -3x
Step-by-step explanation:
in the the equation in the form y = mx +b
m is the slope
b is the y intercept.
__________________________________________________
given slope = -3
thus,
m = -3
the required equation of line is
y = mx +b
put m = -3
y = -3x + b
to find b , we put x = -2, y = -6 as this equation contains point (-2,-6).
-6 = -3*-2 + b
=> -6 = -6 + b
=> b = -6 + 6 = 0
thus. m = -3
b = 0
equation of line
y = -3x
