Answer with explanation:

→The given function is:

       (−6, −13)( −4,−9)( −2,−5)( 0,−1).

Difference in Y values

     = -13 - (-9)=-13+9= -4

    = -9 - (-5)=-9+5 =-4

    = -5 - (-1)= -5 +1= -4

Difference in X value

   = -6 - (-4)=-6+4= -2

   = -4 - (-2)= -4 +2= -2

   = -2 - 0= -2

→Difference in X values as Difference in y values between two points is same.

→The function is Linear.

→Mark is Right.

→Option B:

Mark, because for every 2-unit increase in x, there is an increase in y by 4 .

The number of adults waiting to see the new superhero movie is 62.

<h3>How many adults are waiting in line?</h3>

Ratio expresses the relationship between two or more numbers. Ratio is used to compare two or more numbers. It shows the number of times that one value is contained in another value.

Looking at the ratio given in this question, we know that there are 1 1/2 (3 /2) more children than adults on the line to watch the new superhero movie.

Number of adults waiting to see the movie = (ratio that represents adults / sum of ratio) x total number of people wafting in line

Sum of ratios = 2 + 3 = 5

(2/5) x 155 = 62 people

Consider the function.
dlinn [17]

Answer:

Statement 3

Step-by-step explanation:

y = -2/3x-24

Make x the subject

y + 24 = -(⅔)x

x = -(3/2)(y + 24)

Intersection variables

f^-1(x) = -(3/2)(x + 24)

Slope: -3/2

No domain restrictions

y-intercept: x = 0

-(3/2)(0+24)

-36

(0,-36)

x-intercepts: y = 0

0 = -(3/2)(x + 24)

x = -24

(-24,0)

Linear function, range is all real values of y
