A graph is constructed such that time (in seconds) is the x-variable and distance (in kilometers) is the y-variable. If we plot the distance that light travels on the graph, and it travels at a speed of 300,000 kilometers per second, what is the slope of the graph.?

Question

anonymous · Answer

As 1 second passes by, the light would travel 300,000 km. So the graph would increase like this.|dw:1373909984397:dw|

anonymous · Answer

so by every second(x-value) 300000(y-value) will increase, use these two numbers and find the slope. Rise over Run  :))

(1,300000)

anonymous · Answer

find the slope between two points (0,0) and (1,300000) that is going right up, so with a positive sign

anonymous · Answer

wait im confused.

anonymous · Answer

|dw:1373910683510:dw| graph looks like that. And do you find a slope of a graph when you are given two points? Two points you are given are (0.0) and (1,300000)
So do this (300000-0)/(1-0)=300000
