Answer:
The linear equation for the line which passes through the points given as (-2,8) and $(4,6), is written in the point-slope form as .
Step-by-step explanation:
A condition is given that a line passes through the points whose coordinates are (-2,8) and (4,6).
It is asked to find the linear equation which satisfies the given condition.
Step 1 of 3
Determine the slope of the line.
The points through which the line passes are given as (-2,8) and (4,6). Next, the formula for the slope is given as,
Substitute for
and
respectively, and 4&-2 for
and
respectively in the above formula. Then simplify to get the slope as follows,
Step 2 of 3
Write the linear equation in point-slope form.
A linear equation in point slope form is given as,
Substitute for m,-2 for
, and 8 for
in the above equation and simplify using the distributive property as follows,
Step 3 of 3
Simplify the equation further.
Add 8 on each side of the equation , and simplify as follows,
This is the required linear equation.
Given
The three sides are given 24, 30 and 18.
Explanation
To find the triangle is acute, obtuse or right triangle.
To determine whether the triangle is acute, right, or obtuse.add the squares of the two smaller sides, and compare the sum to the square of the largest side. Since this sum is greater, the triangle is acute.
A
If the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
Now c.
Answer
Hence the sum of the squares of the two smaller sides is equal to the square of the largest side , then it is right triangle.
The correct option is A.
