Which equations represent the line that is perpendicular to the line 5x – 2y = -6 and passes through the point (5,-4)?
check all that apply.
y=-x-2
l2x + 5y = -10
u 2x - 5y = -10
y+4 = (x - 5)
y-4 = (x + 5)

None of these apply

Step-by-step explanation:

Step 1: Bring the equation into the form of y=mx+c

5x-2y = -6

-2y = -6-5x

y = 6+5x

       2

y = 5/2x + 3

Step 2: Identify the slope (m)

Slope is the number with x (5/2)

Step 3: Find slope of the perpendicular line.

Slope of line 2 (perpendicular line) = -1/slope of line 1

m2 = -1/m1

m2 = -1/5/2

m2 = -2/5

Step 4: Find the y-intercept of the perpendicular line,

slope = -2/5

x and y coordinates = (5, -4)

y = mx + c

-4 = -2/5 (5) +c

-4 + 2 = c

c = 2

Step 5: Form equation of perpendicular line

y = mx + c

y = -2/5x + 2

Step 6: Check all equations and match with y = -2/5x + 2

a) y = x - 2 (It does not apply because this equation does not have a slope and y-intercept is not the same).

b) 2x + 5y = -10

   5y = -10 -2x

   y = -2/5x - 2 (This does not apply because the y-intercept does not match-it should be +2))

c) 2x - 5y = -10

   -5y = -10 - 2x

     y = 2/5x + 2 (This does not apply because the slope does not match-it should be -2/5)

d) y + 4 = (x - 5)

  y = x-5-4

  y = x-9 (This does not apply as the slope and y - intercept do not match)

e) y - 4 = (x + 5)

  y = x + 9 (This does not apply as the slope and y - intercept do not match)

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

note: the best i know.
