When is the particle at rest from a velocity graph

The video tutorial explains how to determine when a function is at rest by analyzing its velocity graph. It covers finding the slope of a line using given points and deriving the equation of a line in slope-intercept form. The tutorial also demonstrates how to find the x-intercept by setting y to zero, providing a comprehensive understanding of these mathematical concepts.

When is a function considered to be at rest?

• When the velocity is zero

• When the velocity is decreasing

• When the velocity is at its maximum

• When the velocity is increasing

What is the formula for finding the slope between two points?

• (y2 - y1) / (x2 - x1)

• (x1 - x2) / (y1 - y2)

• (y1 - y2) / (x1 - x2)

• (x2 - x1) / (y2 - y1)

Which form of a line equation is represented by y = mx + b?

• Slope-intercept form

• Intercept form

• Standard form

• Point-slope form

How do you find the x-intercept of a line?

• Set the slope to zero

• Set x to zero and solve for y

• Set both x and y to zero

• Set y to zero and solve for x

What is the x-intercept of the line y = 5x - 21?

• 21/5

• 5

• 5/21

• 0
