Question

select the equation that is perpendicular to y=-1/4x+11 and passes through point (3,5)

Answer 1

this looks familiar...have you done this question before ?

Answer 2

I realized that I put in the slope wrong, and it was supposed to be negative
so kind of

Answer 3

ok....the slope of the equation is -1/4. For perpendicular line we need the negative reciprocal which is 4 (" flip " the slope and change the sign)

y = mx + b (solve for b)
slope(m) = 4
(3,5) x = 3 and y = 5
now sub
y = mx + b
5 = 4(3) + b
5 = 12 + b
5 - 12 = b
-7 = b

perpendicular line is : y = 4x - 7

Answer 4

any questions ?
