Question

What is an equation of the line that passes through the point (−2,5) and is perpendicular to the line whose equation is y = ½ x + 5?
A. y = 2x + 1
B. y = −2x + 1
C. y = 2x + 9
D. y = −2x − 9

Answer 1

perpendicular means the slope is the negative reciprocal

Answer 2

so what's the negative reciprocal of 1/2?

Answer 3

-2

Answer 4

now the equation of line will b\[y-y _{1}=m(x-x _{1})\]

Answer 5

given\[x _{1}=-2,y _{1}=5\]

Answer 6

u found slope\[m=-2\]

Answer 7

Sorry about that and yea just plug them in and solve

Answer 8

thank you
helped a lot

Answer 9

what was your final answer?

Answer 10

y=-2x+1

Answer 11

ya correct

Answer 12

yes!!!
