Two boys are running a speed test on their robotic device for a competition. They need to get an idea of their robot’s speed to determine whether they need to make any adjustments to win the racing portion of the competition. They’ve marked off start and finish lines for a course that’s 200 inches long. They have a stopwatch to measure the time it takes for the robot to go from the start line to the finish line. In past tests, their robot has taken no more than 2 minutes to go 200 inches. They are hoping this test will show improvement in their robot’s speed. If the boys plan to graph the data they collect during the test, which graph uses a degree of precision appropriate to the limits of the test?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

exactly you go it
