Question

Write the equation of the line that is parallel to the line y = 2x + 2 and passes through the point (5, 3).

Answer 1

parallel lines have same slope
so the slope is m=2

use the formula
y-y1=m(x-x1)
y-3=2(x-5)
y-3 = 2x -10
2x-y=7

Answer 2

so the slope is 2 because its next to the x right? y=mx +b?

Answer 3

yes you are right =)

Answer 4

yes thanks :) & how would i do one if they asked me to show them a perpendicular one for example my next problem is this:

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

Answer 5

the product of slopes of two perpendicular lines is (-1)

Answer 6

in this question the slope of the line would be -1/2

Answer 7

so its y = mx + b, what would be b for perpendicular lines?

Answer 8

like would b be 3 or 6?

Answer 9

use the formula
y-y1=m(x-x1)
where x1 and y1 are the coordinates of a point on the line
here x1=6 and y1=3

Answer 10

i dont know how to use that formula :/

Answer 11

y-3=-1/2(x-6)

Answer 12

now just simplify

Answer 13

now what do i do with that? i got y = 2 & 2x -12

Answer 14

Write the equation of the line that is perpendicular to the line y = 2x + 2 and passes through the point (6, 3).

a)y = 2x + 6
b)y = - x + 3
c)y = - x + 6
d)y = 2x + 3

Answer 15

thats the problem but i know its either a or b i just dont know which

Answer 16

in option (c) is it -x or -(1/2)x

Answer 17

i copied it wrong my bad

Answer 18

in option b its -1/2x +3

Answer 19

& option c its -1/2x +6

Answer 20

so if you simplify y-3=-1/2(x-6) you will get
y= -1/2x +6
so it is c

Answer 21

thankssss so much ! are you busy right now ?

Answer 22

yw
no im not...

Answer 23

you have fb i can msg better on ? i have like a couple more doubts :) ? lol
