Add an ice-skating rink there are 22 people who know how to ice skate and 18 people who do not know how to ice skate what is the ratio of people who know how to ice skate and people who do not know how to ice skate

11 : 9

Step-by-step explanation:

Data:

Let: The people who can skate = 22

       The people who do not know how to skate = 18

The ratio of the people who can skate  to people who do not know how to skate is given by:

or 11  : 9

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

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
