The slope of a vertical line is undefined.
Step-by-step explanation:
- The slope of a line in graph or any system could be given as the ratio of the change in the y coordinates to change in the x coordinates
- Here, it is given that the vertical line which passes through a single coordinate in the x-axis. There is only one coordinate is available in the x-axis. There are several points is available in the y coordinates.
- Hence, it is defined as undefined because, if the denominator has zero then it becomes undefined.
- Now, it is understood that the reason why the line has given has a slope undefined.
The question seems incomplete but that could just be my perception.
The slope of y = -4x is -4 as it's the value just in front of the x value. This equation is in the form y = mx+b where m = -4 and b = 0. The m is the slope.
Anything parallel to y = -4x will also have a slope of -4. Parallel lines have equal slopes (but different y intercepts)
Anything perpendicular to y = -4x will have a slope of 1/4. Notice how multiplying the original slope (-4) and the perpendicular slope (1/4) gets you -1. To go from -4 to 1/4, we flip the fraction and the sign. Think of -4 as -4/1 to flip the fraction to -1/4 and then flip the sign to +1/4 or just 1/4.
Classify the two given samples as independent or dependent.
sample 1: the scores of 20 students who took the act
sample 2: the scores of 20 different students who took the sat
Solution: The two given samples are independent samples because in both the samples, the scores of one student will not affect the scores of other students.
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations.
