Answer:
The equation is y=-3x-2
Explanation:
The first we need to know is the equation of a line, and it is y=mx+b
where the m is the slope and b is the interception to the y axis
With the information in the question the slope is -3 and the equation thats equal to m. and the y intercept of -2 thats equal to the b value
then y=-3x-2
