Answer:
Step-by-step explanation:
If a line is parallel to another it must have the same slope
The slope/intercept form of a line is y = mx + b where m is the slope and b the y intercept
The line y = 2x + 5 has slope 2
So the slope of the line that passes through (2,3) must also have the slope 2
We have
y = 2x + b; Substituting x =2, y =3 in this equation gives us
3 = 2 (2) + b or b = -1
Hence the equation of the line is
y = 2x -1
Cross-check
Substitute for x = 2 ==> y = 2(2) - 1 = 3 which is consistent

Answer:
7 years total
Step-by-step explanation:
22200*.1475=3274.5
keep subtracting 3274.5 until you reach 2200$ or less, which is 7 years
Answer:
5$
Step-by-step explanation:
Lets call the childrens ticket x and the adult (x+3).
We then have the equation
200(x+3) + 100(x) = 2100
Divide all by 200
(x+3) + 1/2(x) = 10.5
Subtract 3
x + 1/2x = 7.5
Rewrite it
1.5x = 7.5
Divide by 1.5
x = 5
