PLZ HELP ME PLZ Three toy cars race down a straight path. The distance each car traveled in meters, over time measured in seconds, is shown in the graph below.

1. At what speed is each car traveling? Where can you see each speed in the graph?

2. Explain the significance of the coordinate point (1,r),What do you think the “r” represent?

step-by-step explanation:

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
