Question

ABCD is a rectangle
A is the point= (0,1)
C is the point= (0,5)
the equation of the straight line through A and B is y= 2x+1
(a) find the equation of the straight line through d and C @Godlovesme

Answer 1

so, how do i start this

Answer 2

this is confusing lol i'm trying to figure it out :/

Answer 3

ok, i agree

Answer 4

is there a pcture?

Answer 5

np

Answer 6

so, what do you think

Answer 7

this is the diagram. by the way there is a C on the right side of 6

Answer 8

Ok. I got it

Answer 9

yes, pls share

Answer 10

When you plot these points, and the line.

You are given the information that
a=0,1
c=0,5
b=2,5
d=2,1

to make an equation that passes through both 0,5 and 2,1 (c and d)

get the slope, which is -2x

point slope=

y-1=-2(x-2)

y=-2x+5

Answer 11

And when you go ahead and graph that line, it goes straight through c and D

Answer 12

thank you soo much.
now for part 2
what is the equation of the straight line through B and C

Answer 13

(2,5)(2,1)<<<b and C

a vertical line would go through that

x=?

Answer 14

notice your graph
bear in mind that a rectangle has all right-angles, so all 4 angles are 90 degrees each

so
