Answer 1

Answer:

1.       ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75

1.25(25)+admission=43.75

31.25+admission=43.75

minus 31.25 from both sides

admission=12.50

a.

y=1.25x+12.5

b.

x is number of tickets and y is total cost

c. math, seriously, just read what is above option a (the one in the top of the answer)

if you're too lazy then:

ridescost+admission=total

if x=number of tickets and y is total and cost per ride is 1.25 then

1.25x+admission=y

if we solve

when x=25, y=43.75

2.    

(a)  

m = (y2 - y1) / (x2 - x1) = (4 - 9)/(-2 - 8) = -5/(-10) = 1/2  

(b)  

y - y1 = m(x - x1)  

Using the first given point,  

y - 9 = (1/2)(x - 8)  

Using the second given point,

y - 4 = (1/2)(x + 2)

note they both simplify to  

y = (1/2)x + 5  

(c)  

y = (1/2)x + 5
