Question

Please anyone help me with this question i need it ASAP!! all it’s asking is to Write the equation of a line perpendicular to y=2x-4 and

goes through the point (4,-1). please anyone help meee!!

Answer 1

y =
`-(1)/(2)`x + 1

Explanation:

y = mx + c

Find the reciprocal and change the sign of the gradient (m), which is -
`(1)/(2)`

so

y =
`-(1)/(2)`x + c

Put in your point that you want it to intersect (4,-1):

-1 =
`-(1)/(2)`(4) + c

-1 = -2 + c

-1 + 2 = c

1 = c

y =
`-(1)/(2)`x + 1
