Answer:

y= 3.5x+22.5

Step-by-step explanation:

The standard equation of a line a expressed as y = MX+c

m is the slope

c is the y-intecept

Get the slope

m = y2-y1/x2-x1

m = -9-5/-9+5

m = -14/-4

m = 7/2

Get the y- intercept

Substitute any of the point say (-5,5) and m = 7/2 into the equation y = MX+c

5 = 7/2(-5)+c

5= -35/2+c

5 =-17.5+c

c = 5+17.5

c =22.5

Get the required equation

Recall that y = MX+c

y= 3.5x+22.5

A ticket to a movie theatre for a student is $7. The cost for an adult is $2 more than for a student. How much would it cost 13

MakcuM [25]

Answer: it would cost a total of $194

Step-by-step explanation:

A ticket to a movie theatre for a student is $7. The cost for an adult is $2 more than for a student.

If student ticket costs $x, adult ticket would cost x + 2

This means that the cost for an adult is

7 + 2 = $9

The cost of 13 adult tickets to the movie theatre would be

13 × 9 = $117.

The cost of 11 student tickets to the movie theatre would be

11 × 7 = $77

Total cost of 13 adult tickets and 11 student tickets would be

117 + 77 = $194

Cassandra is creating an animated short film, and she needs 35 frames per second of film. He already has at least 200 frames.

scZoUnD [109]

Answer: C) f ≥ 35s - 200

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

She needs 35 frames (f) per second (s) ( we have to multiply the number of frames by the number of seconds) f ≥ 35s

She has already 200 frames (since we already have, we can subtract that to the needed frames per second)

f ≥35s -200

Feel free to ask for more if needed or if you did not understand something.
