Question

The lines 2x+y =3 , x+2y = 3 , 2x + y =5, x+ 2y = 5 form the Side of

(a) Square (b) Rhombus) (c) Rectangle

Answer 1

B)

Answer 2

:)

Answer 3

@Lyndsey_Coach_xox hw ?

Answer 4

Just find the slope here I guess..

Answer 5

Or distance??

Answer 6

And don't know finally..


ha ha ha..

Answer 7

first confirm that they are a set of parallel lines, this can be done by looking at their slope

now the difference between (squares and rectangles) and a rhombus is that squares and rectangles have 90 degree angles

so in terms of slope, they would be negative reciprocals of each other

if they are 90 degree angles, then just check the distances between the intersections of hte line

Answer 8

I am somewhat right..

Answer 9

Find slope by easier method using the formula:

\[Slope = -\frac{y \; \; coefficient}{x \; \; coefficient}\]

Answer 10

I think x is above..

Answer 11

Yes..

Answer 12

\[Slope = -\frac{x \; \; coefficient}{y \; \; coefficient}\]

Answer 13

much easier if you converted into slope intercept form

Answer 14

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard formula
\[Ax+By=C\]

point-slope formula
\[y-y_1=m(x-x_1)\]

slope-intercept formula
b= y-intercept -- in the form of (0,y)

\[y=mx+b\]

Answer 15

Let @Yahoo! decide..

Answer 16

And if you are given with two points:

\[\frac{y-y_1}{y_2-y_1} = \frac{x-x_1}{x_2-x_1}\]

Answer 17

Sorry, TWO POINT FORM..
