∠KMJ = 180° - 90° (adjacent angles on a straight line)
= 90°
Using Pythagora's Theorem,
KJ² = 6² + 3²
KJ² = 45
KJ = √45
= √9√5
= 3√5
The answer is C. The length of line segment KJ is 3√5 units.
Answer:
4
Step-by-step explanation:
Given:
The graph passes through the points (0,-20) and (4,10).
To find:
The equation of line that most closely represents the line depicted in the graph.
Solution:
If a line passing through two points, then the equation of line is

The given line passes through the points (0,-20) and (4,10). So, the equation of line is




Subtracting 20 from both sides, we get

The function form is

f of x equals fifteen halves times x minus 20.
Therefore, the correct option is B.
