Answer: ![y=8](https://tex.z-dn.net/?f=y%3D8)
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
Where "m" is the slope and "b" is the y-intercept.
We know that this is a horizontal line. This means that:
![m=0](https://tex.z-dn.net/?f=m%3D0)
Knowing that this line contains the point (-4,8) we can substitute this coordinates and
into
, and then solve for "b":
![8=0(-4)+b\\\\b=8](https://tex.z-dn.net/?f=8%3D0%28-4%29%2Bb%5C%5C%5C%5Cb%3D8)
Therefore, the equation of this line in Slope-intercept form is:
![y=(0)x+8\\\\y=8](https://tex.z-dn.net/?f=y%3D%280%29x%2B8%5C%5C%5C%5Cy%3D8)
Answer:
Length of first leg = 1.4feet
Hypotenuse = 4.2feet
Explanation:
Since we are dealing with a right angled triangle, we will apply the Pythagoras theorem to solve the question. According to Pythagoras theorem, the square of the hypotenuse is equal to the sum if the square of the other two legs.
Mathematically, a² = b²+c² where a is the hypotenuse and b, c are the other two legs.
From the question, since hypotenuse of a right triangle is three times the length of its first leg, then a = 3b.
Also the other leg is four feet i.e c= 4
Substituting this values into the Pythagoras formula;
a²=b²+c²
(3b)² = b²+4²
9b² = b²+16
9b²-b² = 16
8b² = 16
b² = 16/8
b² = 2
b = √2
b = 1.4
Since a = 3b
a = 3(1.4)
a = 4.2
Hence, the length of the first leg is 1.4feet and that of the hypotenuse is 4.2feet both to the nearest tenth.
