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

The y intercept of the line is ___ , and the slope of the line is ___.

CaHeK987 [17]

Answer:

The y-intercept of the line is 1/2, and the slope of the line is 5.

Step-by-step explanation:

$2y+2=10x+3$

$2y=10x+3-2$

$2y=10x+1$

$y=\frac{10x+1}{2}$

$y=\frac{10x}{2} +\frac{1}{2}$

$y=5x+\frac{1}{2}$

$y=mx+b$

$m$ is the slope.

$b$ is the y-intercept.
