The slope of a perpendicular line is the negative reciprocal of the normal slope.  For example, 3/7 would become -7/3.  

Because the slope of this line is 1/5, the slope of a line that is perpendicular to it is -5.

Now, to find the equation of the line, we need to find the y intercept.  Since the line passes through (0,0), that is the y intercept.  Now, we can make the equation of the line.

y = -5x

PWEASE HELP ASAP my friends and I cant figure this out I'm hoping one of u guys can
Degger [83]

The number of viruses was 4000 times greater than number of protozoa.

Step-by-step explanation:

Given,

Number of protozoa = 5*10^5

Number of viruses = 2*10^9

Let,

x be the number of times number of viruses is greater than number of protozoa.

Number of viruses = Number of time * Number of protozoa

2*10^9=(5*10^5)x

Dividing both sides by 5*10^5

\frac{2*10^9}{5*10^5}=\frac{(5*10^5)x}{5*10^5}\\\\4*10^3= x\\x=4*10^3 \\x=4000

The number of viruses was 4000 times greater than number of protozoa.

In order to inscribe a circle in a triangle which line must you construct?
Galina-37 [17]

You need to construct at least 2 angle bisectors to help locate the incircle's center (aka the "incenter"). The incircle is the largest circle possible that is inside the triangle, that doesn't overflow or spill outside of the triangle. An angle bisector cuts an angle in half.

Using the formula y=mx+b whats the equation of (2,-8) with a slope of -1?
Leona [35]

Answer:

y = -x - 6

Step-by-step explanation:

Given:

  • slope = -1
  • point (2,-8)

From:

\displaystyle \large{y=mx+b}

where m = slope and b = y-intercept. Therefore:

\displaystyle \large{y=-1x+b}\\\displaystyle \large{y=-x+b}

Since the equation passes through a point (2,-8). Substitute x = 2 and y = -8 in and solve for b:

\displaystyle \large{-8=-2+b}\\\displaystyle \large{-8+2=b}\\\displaystyle \large{b=-6}

Then substitute b-value in the equation:

\displaystyle \large{y=-x+b}\\\displaystyle \large{\therefore y=-x-6}

Hence, the equation is y = -x - 6
