Can you help me with the first two questions?

Since it is unknown how much they paid for the original painting, we'll use x to represent that. 2x+1000 is equal to 55,000, so that is our equation.
2x+1000=55,000
2x=54,000
x=27,000
The Leungs originally paid $27,000 (answer choice B)
Question #12:
-4(x-11)=16
Apply the distributive property.
-4x+44=16
-4x=--28
x=7
Since x=7, let's figure out which answer choice can be possible by subsituting the x in each answer choice with 7.
Answer choice F: Does 7-11=4? No, so this answer can't be correct.
Answer choice G: Does 7-11=-4? Yes! This answer is correct.
Answer choice H: Does -28-11=16? No, so this answer can't be correct.
Answer choice I: Does -28+44=64? No, so this answer can't be correct.
It is answer choice G.

The correct interpretation is that the slope of the line is indeed 15, indicating that the cost of one admission ticket is $15, and point (1, 15) represents the unit rate.
The correct answer is option B.
The given graph illustrates the relationship between the number of people in a group and the cost of admission tickets. The statement correctly identifies that the slope of the line on this graph represents the unit rate of admission tickets.
The slope of a line on a graph signifies the rate of change between the two variables involved. In this context, the horizontal axis (x-axis) represents the number of people in a group, while the vertical axis (y-axis) represents the cost of admission tickets.
To compute the slope, you select two points on the line. The statement correctly utilizes the points (0, 0) and (1, 15) for this purpose. The slope formula, which is the change in y divided by the change in x, is applied as follows:
Slope = (y2 - y1) / (x2 - x1)
In this instance, x1 = 0, y1 = 0, x2 = 1, and y2 = 15. Substituting these values into the formula yields:
Slope = (15 - 0) / (1 - 0) = 15 / 1 = 15
This signifies that for each additional person in the group, the cost of admission tickets increases by $15. Consequently, $15 represents the cost of one admission ticket, and the point (1, 15) represents the unit rate.
Therefore, the conclusion that option B is the answer is accurate.
