PQ =  \sqrt{(3-0)^2+(2-1)^2}= \sqrt{9+1}= \sqrt{10}    \\ QR= \sqrt{(5-3)^2+(-4-2)^2}= \sqrt{4+36}= \sqrt{40} \\PR= \sqrt{(5-0)^2+(-4-1)^2}= \sqrt{25+25}= \sqrt{50}

PR is the longest side.
The triangle will be right if
PQ² + QR² = PR²

PQ² + QR² = (√10)² + (√40)² = 10 + 40 = 50
PR² = (√50)² = 50
50=50  so, ΔPQR is <span>a right triangle.</span>

PR is the longest side.

The triangle will be right if

PQ² + QR² = PR²

PQ² + QR² = (√10)² + (√40)² = 10 + 40 = 50

PR² = (√50)² = 50

Find the slope of the line that passes through (10, 8) and (1, 1).
Nana76 [90]

Answer:

2/3

Step-by-step explanation:

the formula to find slope is y1-y2/x1-x2.

The ordered pairs are (10,8) and (1,1)

                                     (x, y).        (x, y)

So it would be: 8-1 OVER 10-1

=6/9 which simplifies to 2/3

so your slope would be 2/3
