Lines RS, TV, and SW are shown. On a coordinate plane, 3 lines are shown. Line R S goes through (negative 8, 6) and (2, 6). Line T V goes through (negative 6, negative 4) and (8, negative 4). Line S W goes through (2, 6) and (2, negative 8). Which statements are true about these lines? Select three options. Line RS has a slope of 6. Line SW has an undefined slope. Line TV has a slope of 0. Lines RS and TV are parallel. Line SW is perpendicular to line RS, but not to line

Three true statements about the lines are;

1) Line SW has an undefined slope

2) Line TV has a slope of 0

3) Lines RS and TV are parallel

Step-by-step explanation:

The coordinates of the points the three lines go through are;

The points line RS go through = (-8, 6) and (2, 6)

The points line TV go through = (-6, -4) and (8, -4)

The points line SW go through = (2, 6) and (2, -8)

The slope of a line with points (x₁, y₁) and (x₂, y₂) is given by the following equation;

The slope of line RS = (6 - 6)/(2 - (-8)) = 0

The slope of line SW = (-8 - 6)/(2 - 2) = -14/0 = ∞ (undefined)

Therefore, line SW has an undefined slope

The slope of line TV = (-4 - (-4))/(8 - (-6)) = 0/14 = 0

Therefore, line TV has a slope of 0

Line RS and line TV have the same sloe (0) and are therefore parallel

Therefore, lines RS and TV are parallel.

- "runner b is moving at a slower rate."

- "the graphs shown are graphs of distance(km) against time(min).

the slopes of this graphs are are given by:

slope = (change in y)/(change in x)

= (change in distance)/(change in time)

this is the formula for finding the speed. so, the slope of these graphs represent the speed of the runner.

taking each division in the graph to represent 1 on both axis:

runner a ⇒ speed = (2-0)/(1-0)

= 2/1

= 2 km/min

runner b ⇒ speed = (3-0)/(3-0)

= 3/3

= 1 km/min

this shows that   runner b is moving at a slower rate."
