Step-by-step explanation:
f(x) = 1/2 x é uma função do 1° grau com coeficiente linear=1/2.
1.
Parallelogram with base a = 20 in. and height h = 16 in.
Triangle with base a = 20 in. and height b = 8 in.
so:

2.
Trapezoid with base b₁ = 14 cm, base b₂ = 4 cm and height h = 10 cm
Triangle with base b₁ = 14 cm and height x = 18 cm - 10 cm = 8 cm
so:

3.
We have three rectangles:

Answer:
speed
Step-by-step explanation:
In a distance-time graph:
Distance is the y-variable (dependent)
Time is the x-variable (independent)
The slope of a line is rise/run, or can also be calculated with this equation, where "m" is slope:

slope = y-variables / x-variables
slope = distance / time
If you divide distance by the time it took to get that far, you will find how fast you got there. This is called the speed.
You might also see this formula:
k = d/t
In the options, "time" and "distance" would not make sense, because those are the variables on the x-axis and y-axis.
