Answer:
Graph A
Explanation:
By carefully observing the graph shown, there is a censtant rate of change of speed with time (i.e the slope)
Considering the points (0, 0) and (2, 4)
[tex]\begin{gathered} The\text{ slope, m=}\frac{y_2-y_1}{x_2-x_1} \\ \\ m=\frac{4-0}{2-0} \\ \\ m=\frac{4}{2} \\ \\ m=2 \end{gathered}[/tex]
The equation of a line is given as:
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ \\ y-0=2(x-0) \\ \\ y=2x \end{gathered}[/tex]
The only graph that represents the equation y = 2x is graph A
