which of the following is the equation of a line perpendicular to the line y= -x+1 and passes through the points (4,1)

y= x-3

Step-by-step explanation:

y = -x+1.

y=mx+c

m= -1.

m1 = -1

for perpendicularism, m2 = -1

_

m1

m2= -1

__

-1

m2= 1

y-y1=m(x -x1)

x1= 4

y1=1

y-1= 1(x-4)

y-1=x-4

y=x-4+1

y= x-3.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
