Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Standard Form: Ax + By = C
Step-by-step explanation:
<u>Step 1: Define equation</u>
Slope-Intercept Form: 2 + (1/2)x = y
<u>Step 2: Find Standard Form</u>
- Rewrite: y = (1/2)x + 2
- Subtract 1/2x on both sides: y - 1/2x = 2
- Factor negative: -(1/2x - y) = 2
- Divide both sides by -1: 1/2x - y = -2

Answer:
20000000
Step-by-step explanation:
Answer:
£11.20 – £33
Step-by-step explanation:
The minimum value in the table is £11.20. The maximum value in the table is £33. The range of costs is the interval bounded by these values.
The difference between the maximum and minimum is £33 -11.20 = £21.80.
_____
"Range" has two possible meanings here. When "range" is applied to function values, it has one meaning. When "range" is applied to statistical data, it can have a different meaning.
- The extent of function values, from the minimum to the maximum.
- The difference between the maximum and the minimum.
Choose the meaning as defined in your curriculum material.
