someone help. i’m bad at math.

Step-by-step explanation:
when perpendicular, u must use m1m2=-1
so , (⅓)(m2)=-1
m2= -3
y-y1=m2(x-x2)
y-1=-3(x-0)
y=-3x+1
Answer:
y = -3x + 1
Step-by-step explanation:
to be perpendicular the multiplication of the gradiens should be -1
m1 × m2 = -1 , m1 = 1/3
1/3 × m2 = -1
m2 = -3
and required equation passes through the point.( 0,1)
y = m2 x + c2
1 = -3 (0) + c2
c2 = 1
so the equation
y = -3x + 1
