Samantha is going on vacation for the summer and is trying to choose between two different plans. The first plan costs $450 for
ziro4ka [17]
Pretend the cost of the hotel is called "x" and the amusement park is "y"
make the equations.
450=3x+2y  and  700=5x+3y
since you're solving for amusement park, you basically just solve for y
multiply the first equation by 5 and the second equation by 3.
2250=15x+10y  and  2100=15x+9y
these are a system of equations so subtract one from the other to cancel the x values away.
150=y   so the answer is that a day trip to the amusement park costs $150

Which of the following is an equation of the line that crosses through (-3,4) and (3,6)?
Mama L [17]

Answer:

y=(1/3)x+5

Step-by-step explanation:

Slope-intercept: y=mx+b

m=((y2-y1)/(x2-x1)) = (6-4)/(3+3)= 2/6= (1/3)

y=(1/3)x+b

plug in one of the points (3,6)

6=(1/3)(3)+b

6=1+b    5=b
