Well, first, the equation that you are looking for is Y = MX + B. To find B, look at the first dot on the Y-axis. It starts at positive 3, so, you know your equation will end with +3. Next, to find MX, start at the either dot, and find the Rise/Run. In this particular equation, the rise is 1, and, the run is -2, because it's going backwards (negative line). Meaning, the line's equation would be, f( x )= -1/2x + 3.

The Z-score is calculated by the formula below
Step 2: Substitute the given parameters in the formula
Hence, the z-score of a person who scored 145 on the exam is -0.5
Answer:
No, 0.333 is a rational number, not a natural number
Step-by-step explanation:
Gradient =2 because the slope is 2 units. Y-intercept = -2 because it crosses the y-line at -2.
