The equation of a line is y = -3x - 2. What are the slope and the y-intercept of the line? slope = -3 and y-intercept = 2 slope = 3 and y-intercept = -2 slope = 3 and y-intercept = 2 slope = -3 and y-intercept = -2

Answers

Answer:

slope -3 and y-intercept -2

Step-by-step explanation:

The slope:

the general linear function is y=mx+n where m is the slope

so slope = -3

y intercept is when x=0

y=-3*0-2

y=-2

A spinner with 10 equally sized slices has 2 red slices, 4 yellow slices, and 4 blue slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a red slice?

Answers

The probability that the dial stops on a red slice, when it is spun and stops on a slice at random is 1/5.

How to get probability of an event?

Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.

A spinner with 10 equally sized slices has 2 red slices, 4 yellow slices, and 4 blue slices.

The total number of slices is 10 and the total number of favorable outcome to get a red slice is 2. Thus, the probability that the dial stops on a red slice is,

$P=(2)/(10)\nP=(1)/(5)$

Thus, the probability that the dial stops on a red slice, when it is spun and stops on a slice at random is 1/5.
