Slope-intercept form is <em>y = mx + b</em> where m is the slope and b is the y-intercept. (the value of y when x = 0)
To find the slope, use the slope formula,
, where (x¹, y¹) and (x², y²) are your two points.
For (-2, 6) and (2, 14):
As a fraction, we would write the slope 2/1, but dividing by 1 is redundant when writing the actual equation.
Since slope is rise over run, we can interpret this slope as <em>"when y changes by 2, x changes by 1 (and vice versa)"</em>
Let's take one of our points, how about (-2, 6), and find our y-intercept from this.
We want to add 2 to x. According to our slope, this means adding 4 to y.
Our y-intercept is at (0, 10), with the value we put into our equation b = 10.
Final equation:
y = 2x + 10
Answer: Its the first and third one.
Step-by-step explanation: Lol nope
You commented that part of the instruction included "If the theorem cannot be applied, explain the reason."
The theorem cannot be applied. Since this is not a right triangle, we cannot solve using the Pythagorean Theorem unless we are given a height. If we have the height of this triangle, then we can break it into two different right triangles and solve.
What is a right triangle? A right triangle is a triangle that has an angle measurement of 90 degrees.
In summary, this is an isosceles triangle and the Pythagorean Theorem only applies to right triangles.
Answer:
Step-by-step explanation:
Diameter of cone = 24 units
Radius of cone (r) = 24/2 = 12 units
Height of cone (h) = 28 units
