Answer:
Step-by-step explanation:
To find the slope, use the equation
where (-1, 7) and (4, -1) is (x1, y1) and (x2, y2) respectively.
Hence, the slope will be

Answer:
The length of the missing leg is 22.20.
Step-by-step explanation:
You can use the Pythagorean theorem to solve for the length of the missing leg:
+ = , where <em>a</em> and <em>b</em> are the lengths of the legs and <em>c</em> is the length of the hypotenuse.
First, substitute the lengths of the given values:
+ =
Next, simplify the exponents on both sides:
36 + = 529
Then, isolate <em>b </em>by subtracting 36 from both sides:
= 493
Next, take the square root of both sides:
<em>b</em> =
Finally, take the square root and round according to the given directions:
<em>b</em> = 22.20
13 - 7 = (10 + 3) - 7 = (10 - 7) + 3 = 3 + 3 = 6
