Answer:
y=-3x+5
Step-by-step explanation:
So, with perpendicular equations, you flip the slope, so 1/3 becomes 3/1, and make it negative, and if it is already negative, you make it positive. So, since we have the slope, move on to the b=y-mx, so b=-4-(3)(-3), multiply to get b=-4-(-9), which makes our y-int 5.
