Answer:
Slope: 2
a: 5
b: 6
y-coordinate when x = 0: -2
Step-by-step explanation:
To find the slope, you need to divide the change in the y values between two points on a line by their change in x values. The two complete points given are (6, 10) and (2, 2), so doing this for them would be...
(10-2)/(6-2) = 8/4 = 2, so your slope is 2
To find a, you must use this slope by counting from one of the points. For every one you go to the right, you go up two. So, how many times do you need to go up 2 (slope), from 2 (starting point's y coordinate), to get to 8 (target point's y coordinate)? (8-2)/2 = 6/2 = 3, so 3 times. Add that to 2 (starting point's x coordinate) to get 5, so a is 5.
To find b, you can just use (6, 8). You know you're going to the LEFT one, so you must go DOWN 2. Subtract 2 from 8 to get 6.
For the last question, do the same with (2, 2). You're going LEFT 2, so you're going DOWN 4. Subtract 4 from 2 to get -2.

The maximum profit for 1 tour would be $2650
if there are 90 seats and 10 deluxe seats must be sold, you have to multiply 10 times 25 which gives you 250.
if there are 90 seats, 10 must be deluxe (which is cheaper), and you are trying to find the max profit for 1 tour, then 80 of the seats must be economy seats.
to find out how much 80 economy seats would cost you need to multiply 80 times 30 which gives you 2400.
then you need to add the profit of 80 economy seats and 10 deluxe seats and that would give you $2650
and $2650 would be the max profit you could make for 1 tour.
Answer:
5. 3/5-2/5=1/5; answer is 1/5
6.7/10-3/10=4/10; answer is 2/5(simplify)
7.5/6-4/6=1/6; answer is 1/6
8.3/4-2/4=1/4; answer is 1/4
Step-by-step explanation:
Explanation is above, when subtracting fractions remember that the denominator must be the same and you can subtract the numerator.
Hope this helps!
(a) is the first one. 48 I would say 8 mins
(b) is the second one. 10 I would say is 96
