Find the distance between the two points rounding to the nearest tenth (if necessary)
Andrews [41]

Answer:

The answer is

<h2>2.8 units </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  }  \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-3,3) and (-1,5)

The distance is

d =  \sqrt{( { - 3 + 1})^{2} +  ({3 - 5})^{2}  }    \\  =  \sqrt{ ({ - 2})^{2} + ( { - 2})^{2}  }  \\  =  \sqrt{4 + 4}  \\  =  \sqrt{8}  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 2 \sqrt{2}  \:  \:  \:  \:  \:  \:  \\  = 2.82842

We have the final answer as

<h3>2.8 units to the nearest tenth</h3>

Hope this helps you

Write the point slope form of the line that passes through (-8,2) and is perpendicular to a line with a slope of -8
Fynjy0 [20]

Answer:

y - 2 = \frac{1}{8}(x +8)

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes. Since the slope of one line is -8, its perpendicular line will have the slope of 1/8.

Substitute m = 1/8 and (-8,2) into the point slope form of a line.

y - y_1 = m(x-x_1)\\y - 2 = \frac{1}{8}(x --8)\\y - 2 = \frac{1}{8}(x +8)

Which of the following graphs would represent the solution set for y &gt; 4/5 x – 1?
vlada-n [284]
A>0 so function rises

b=-1 so for x=0 ⇒ y<-1

we look for y that is above the line

so answer is the last <span>graph.</span>
