1) -10x+y=4

Now, you should substitute x in every situation.

* x=-2 => -10*(-2)+y=4... 20+y=4... y=-16

* x=-1 =>-10*(-1)+y=4... 10+y=4... y=-6

*x=0 => -10*0+y=4... y=4

* x=1 => -10*1+y=4... -10+y=4... y=14

* x=2 => -10*2+y=4... -20+y=4... y=24

2) -5x-1=y

For example: x=0

-5*0-1=-1

Which points are exactly 10 units from the point (–8, –2)? Check ALL that apply.

Archy [21]

Answer:

The points that are exactly 10 units from the point (–8, –2) are (2, –2) and (–8, 8).

Step-by-step explanation:

The distance formula is;

d= $\sqrt{( x_{2}-x_{1} )^{2}-(y_{2} -y_{1} )^{2} }$

So for distance between: (–8, –2) and (2, –2) is:

d= $\sqrt{( 2-(-8))^{2}-(-2 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit

Similarly for distance between: (–8, –2) and (–8, 8) is,

d= $\sqrt{( -8-(-8))^{2}-(8 -(-2) )^{2} }$

d= $\sqrt{100}$

d= 10 unit
