SUMMARY

The equation Y = mx + b represents a linear relationship in position-time graphs, where 'm' denotes the slope of the line and 'b' signifies the y-intercept. The y-intercept is the point where the line intersects the y-axis, occurring at x = 0. Understanding this equation is crucial for interpreting motion in physics, as it allows for the visualization of position changes over time. Tools like Wolfram Alpha can be utilized to manipulate values of 'm' and 'b' to observe their effects on the graph.

i am currently taking physics 11. i have seen this equation before, but my class is at such a fast pace i couldn't fully learn what this equation ment. i am working on a position time graph, what exactly does this equation mean? what does the letter " b " resemble?

That's the equation of a straight line on the x-y plane. m is the slope of the line. b is the y-intercept.
 
and the y intercept is where the line crosses the y-axis right?

Right. Also where x = 0.
