Question

Which is the equation to the line passing through points (2, -7) and (5, -1)?

y = 2x - 8
y = - 2x + 9
y = 2x - 11
y = - 2x + 6

Answer 1

first take out the the slope by this formula
m= y2 - y1 /x2 -x1
let
(x1,y1)=(2,-7)
(x2,y2)=(5,-1)

Answer 2

so the slope is m=2
alright!!!

Answer 3

now use the point slope formula here
pick the slope and only any one point from the two given points
(y-y1)=m(x-x1)
now put them in it and get the answer

Answer 4

let (x1,y1)=(5,-1)
m=2
then
y+1=2(x-5)
y+1 =2x-10
y=2x-10 -1
y=2x-11 is the correct answer

Answer 5

@kellyconnelly have u got it????

Answer 6

yes thanks you were helpful:)

Answer 7

welcome my dear @kellyconnelly

Answer 8

What is the equation of a vertical line passing through (1, 7)?

y = 7
x = 1
y = 1
x = 7

Answer 9

for that question would you do the same thing?

Answer 10

it only gives me one point so idk how to find slope?

Answer 11

here it is not given either the vertical line is on the y - axis or far from it

Answer 12

soooo what do i do??

Answer 13

x=1 is the correct answer

Answer 14

@kellyconnelly did u guys figure it out?

Answer 15

A vertical line passing through the point (4, -3) means that for any value of y, x is always going to be equal to 4; the formula may be generally written as x = a where a is the x-intercept.. An x-intercept is the value of x when y = 0. As we already stated, for any value of y, x = 4. Therefore, this vertical line will pass through the point (4,0). You can write the equation as x = 4.

Answer 16

. Graphing this equation in a graphing calculator requires you to "trick" the graphing calculator because in the "graph" menu you only have the option of writing in equations in the form y =, which you can't do for this problem

Answer 17

wut

Answer 18

lol........ it is so simple

Answer 19

show me how you would solve it please

Answer 20

\[-7 = 2(2) - 11.......................-7 = 4 -11\]
\[-1 = 2(5) -11.................... -1 = 10-11 \]

Answer 21

the answer would be C @kellyconnelly ..........

Answer 22

@kellyconnelly @driftracer305 is correct because here it is asking about vertical line and we know that on thhe vertical line the x=0 then y=1
clapping for @driftracer305

Answer 23

so its y=1 not x=1 ????

Answer 24

yes it is y=1
my apologize i forget the major thing that it is asking about the vertical line

Answer 25

oh its fine thank you!!
