Find the distance between the two points in simplest radical form.<br> (7,2) and (-1, -3)

Paul [167]

Answer:

The answer is

<h2> $\sqrt{89} \: \: \: \: units \\$ </h2>

Step-by-step explanation:

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

$d = \sqrt{ ({x_1 - x_2})^{2} + ({y_1 - y_2})^{2} } \\$

where

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

From the question the points are

(7,2) and (-1, -3)

The distance between them is

$d = \sqrt{( {7 + 1})^{2} + ({2 + 3})^{2} } \\ = \sqrt{ {8}^{2} + {5}^{2} } \\ = \sqrt{64 + 25} \\ = \sqrt{89} \: \: \: \: \: \: \: \: \: \:$

We have the final answer as

$\sqrt{89} \: \: \: \: units \\$

Given a line with slope of 5 and y-intercept of -1, which of the ordered pairs given below would NOT be on the line?

Vedmedyk [2.9K]

Answer:

(4, 18)

Step-by-step explanation:

We can just pluck the x values into the equation: y = 5x -1 to see if the y values fit.

1. y = 5(4) - 1

= 20 - 1

= 19 (Nope, 18 is not 19)

2. y = 5(3) - 1

= 15 - 1

= 14 (Yep, same as option)

3. y = 5(0) - 1

= 0-1

= -1 (Yep, same as option)

4. y = 5(2) - 1

= 10 - 1

= 9 (Yep, same as option)
