Answer:

c = 2\sqrt{5

Step-by-step explanation:

Given

a = 2

b = 4

c = hypotenuse

Required

Find c

Using Pythagoras theorem, we have:

c^2 = a^2 + b^2

Substitute values for a and b

c^2 = 2^2 + 4^2

c^2 = 4 + 16

c^2 = 20

Take square roots of both sides:

c = \sqrt{20

Express 20 as 4 * 5

c = \sqrt{4 * 5

Split surd

c = \sqrt{4} * \sqrt{5

Take square root of 4

c = 2 * \sqrt{5

c = 2\sqrt{5

<h3>Answer: Choice C</h3>

=============================================

Explanation:

Choices A, B and D are not true because of the negative y values. The result of an absolute value is never negative. So we can rule out choices A, B, and D. We have choice C as the only thing left, so this must be the answer.

-------------

Another way to see this is by plugging in each x value to see what y value comes out.

  • If x = -2, then y = |5*x| = |5*(-2)| = |-10| = 10
  • If x = -1, then y = |5*x| = |5*(-1)| = |-5| = 5
  • If x = 0, then y = |5*x| = |5*0| = |0| = 0
  • If x = 1, then y = |5*x| = |5*1| = |5| = 5
  • If x = 2, then y = |5*x| = |5*2| = |10| = 10

The y outputs from top to bottom are: 10, 5, 0, 5, 10

This matches with what choice C shows.

Using the Slope Equation
Pick two points on the line and determine their coordinates.
Determine the difference in y-coordinates of these two points (rise).
Determine the difference in x-coordinates for these two points (run).
Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).
