Step-by-step explanation:
The graph of a <u>proportional linear relationship</u> is a line that <u>passes through the origin</u> (0, 0).
From inspection of the given tables, the <u>linear equations</u> for each table of points is:
- Table 1: y = x + 1
- Table 2: y = x/2
- Table 3: y = x + 2
- Table 4: y = 2x + 1
The only equation for which y = 0 when x = 0 is y = x/2 → Table 2.
Given points from Table 2:
- (2, 1)
- (4, 2)
- (6, 3)
- (8, 4)
To <u>graph the line</u>, plot the given points and draw a line through them (see attached).

Three feet below the initial elevation
Step-by-step explanation:
The initial elevation is 224 feet.
We take descent to be negative and ascent to be positive.
The numerical addition expression is
We simplify this to obtain:
The negative sign means Sally is 3 feet below his initial elevation
