Do you want the equation of the line given the slope and a point it goes through?
y - y1 = m (x - x1)
y - 16.5 = 1.75 (x - 10)
y - 16.5 = 1.75x -17.5
y = 1.75x - 1
Answer:
23. x = 4; DE = 44
24. x = 25; DS = 28
Step-by-step explanation:
23. Point S is the midpoint of DE, so ...
DS = SE
3x +10 = 6x -2
12 = 3x . . . . . . . . . add 2-3x
4 = x . . . . . . . . . . . divide by 3
Then DS has length ...
DS = 3x +10 = 12 +10 = 22
and DE is twice that length, so ...
DE = 44
__
24. DS is half the length of DE, so is ...
DS = DE/2 = 56/2
DS = 28
Then x can be found from ...
DS = x +3
28 -3 = x = 25 . . . . . substitute value for DS

<em>Comment on problem 24</em>
Sometimes it is easier to work parts of a problem out of sequence. Here, finding DS first makes finding x easier.

Answer:
This says middle school.. What grade are you in? I am in 8th grade and do not know any of that...
I have never seen work near that.........
The equation is : C=250t +125 where C is the cost and t represent the number of tickets purchased.
Step-by-step explanation:
Let the cost of premium seat ticket be C
Let the number of tickets a fan buys to be t
Then, presenting the information as ordered pairs of coordinates (x,y) will be;
Fan 1, (3,875)
Fan 2, (8,2125)
Plot the ordered pairs as coordinates on a graph tool, find the slope of the linear graph and equation in slope intercept form as;
m=Δy/Δx
m=2125-875/8-3
m=1250/5
m=250
Equation of the graph,
Δy/Δx=250
y-875/x-3 =250
y-875=250(x-3)
y-875=250x-750
y=250x-750+875
y=250x+125
C=250t +125 where C is the cost and t represent the number of tickets purchased
