What does it mean when the 2 runners graphs cross?
What does it mean when the two runners’ graphs cross? When the two runners graphs cross this means that in the graph above that runner 2 was behind but caught up and ran past runner 1 beating him to the finish line (40 meters).
How many times does one runner pass another?
So you were right. They pass each other 12 times.
How are distance time graphs useful?
A distance-time graph is a useful way to represent the motion of an object. It shows how the distance moved from a starting point changes over time. distance travelled is plotted on the vertical (y) axis. time taken is plotted on the horizontal (x) axis.
What does the Y intercept tell you about the runner?
What does the y-intercept tell you about the runner? The y intercept tells us how many meters the runner has ran or how far the runner will run.
Who ran faster Max or Molly?
Max ran 50 meters in 10 seconds and Molly ran 30 meters in 5 seconds.
Whats faster 50 meters in 10 seconds or 30 meters in 5 seconds?
50 meters per 10 seconds is 5 meters per second, and 30 meters per 5 seconds is 6 meters per second.
What does ay intercept look like?
Every straight line can be represented by an equation: y = mx + b. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
What does Y-intercept represent?
The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.
Why is the Y-intercept important?
In the particular context of word problems, the y-intercept (that is, the point when x = 0) also refers to the starting value. For a time-based exercise, this will be the value when you started taking your reading or when you started tracking the time and its related changes.
What does the B in Y MX B stand for?
y-intercept
Why is the Y intercept 0?
The Y intercept of a straight line is simply where the line crosses the Y axis. In the above diagram the line crosses the Y axis at 1. The Y intercept is equal to 1 and the point is written as (0,1). Notice that for the y-intercept the x-coordinate of the point is always zero..
What happens if Y intercept is 0?
If a line has no y-intercept, that means it never intersects the y-axis, so it must be parallel to the y-axis. This slope of this line is undefined. If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis. This means it is a horizontal line, such as .
What happens when y equals 0?
But you can also remember a shortcut, which is that a slope of zero will always be represented as a horizontal line and therefore, when y=0, the graph will essentially show a line through the x-axis.
Is the Y intercept a zero?
The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero. The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.
