Question

(1,6), (4,6), (2,1) how do i find the coordinates of the fourth point? can anyone show me.

Answer 1

what kind of graph is it?

Answer 2

linear
quadratic?

Answer 3

is it a quad.?

Answer 4

linear

Answer 5

plot the points

Answer 6

the draw the line

Answer 7

kind of like connect the dots

Answer 8

is there a way of doing by showing an equation

Answer 9

the continue drawing

Answer 10

sure there is

Answer 11

how
is there a formula i have to follow

Answer 12

point slope formula

Answer 13

wait no
lemme think again

Answer 14

ya try point slope formula

Answer 15

dont know it

Answer 16

y-y1=m(x-x1)

match first (x,y)
second (x,y)
------

Answer 17

i got thanks alot

Answer 18

what i mean match is
subtract first x from second x
and so on

Answer 19

what you will get is the slope

Answer 20

and you can put it in slope intercept form
which would be much easier to work with (in my opinion)

Answer 21

y would equal 0 when looking for x intercept and vice versa right?

Answer 22

By drawing I think answer is (5,1)

Answer 23

yeah but i need to show the equation so i can understand how to work the equation

Answer 24

technically if its a line on a coordinate plane

the answer is infinite

Answer 25

not just 4

Answer 26

ok

Answer 27

if you draw any line

how many points can you name

Answer 28

that was just an example

Answer 29

what shape does it make?? There should be something like a rhombus, or a rectangle, etc. otherwise only three points are enough to make a triangle :)

Answer 30

rectangle

Answer 31

Draw a rough sketch and give the names A,B,C and D(x,y) to the points. Calculate the length of AB and equate it with CD to obtain an equation. Then find the length of BC and equate it with AD to find another equation. Solve both equations to find the value of x and y.

Answer 32

how i do that

Answer 33

I agree with MarinaDL the answer is (5,1).

Have you drawn the points onto graph paper?

Answer 34

Draw the figure as above. Find the AB and BC using distance formula. Find the opposite sides to AB and BC in terms of x and y. Equate the pair of opposite sides to obtain two equations. Solve those equations to find x and y. (x,y) is the required point.
