Question

"without graphing determine the quadrient in which the point (x,y) lies if x<0 and y<0 "
A.II
B.IV
C.I
D. III
Please help!

Answer 1

It is on the vertex I think.

Answer 2

its the bottom left quadrant...whichever one that is

Answer 3

It is on three then. texaschic101 is right.

Answer 4

I just looked it up...it is 3

Answer 5

Yeah

Answer 6

@texaschic101 @Headlessdust41 Thank you! Mind helping me with some other questions?

Answer 7

Sure.

Answer 8

whatcha got

Answer 9

On which of the following lines does the point (7,1) Lie?
A.Y-5x=4
B.Y= X- 10
C.Y= -4x+3
D. Y= -X +8

Answer 10

Thank you again!

Answer 11

we are going to have to sub our points in to see ...(7,1) x = 7 and y = 1

y - 5x = 4
1 - 5(7) = 4
1 - 35 = 4
-34 = 4 (not this one)

y = x - 10
1 = 7 - 10
1 = -3 (nope)

y = -4x + 3
1 = -4(7) + 3
1 = -28 + 3
1 = - 25 (nope)

y = -x + 8
1 = -7 + 8
1 = 1 (It would have to be the last one..lol)

Answer 12

Last one(:

Find the Slope of the line through (-9, -10) and (-2, -5).
A.-5/7
B.7/5
C.5/7
D.-7/5

Answer 13

Thank you so much!!! It means it a lot!

Answer 14

slope formula is : slope = (y2 - y1) / (x2 - x1)
(-9,-10) x1 = -9 and y1 = -10
(-2,-5) x2 = -2 and y2 = -5
now we sub
slope = (-5 - (-10) / (-2 - (-9)
slope = (-5 + 10) / (-2 + 9)
slope = 5/7 (C)

I don't mind helping when I can :)
