Please help me!?!? I don’t understand, The graph represents the path of a rock thrown from the top of a cliff by a hiker:

Step-by-step explanation:

From the statements in the problem, we think your graph looks something like the one below. It has height on the vertical axis and time on the horizontal axis.

At the left side of the graph, where time is zero, the height is 53 feet. That is the height of the rock at the time it is thrown, so we know the y-value of the y-intercept (A) tells us the rock was thrown from a height of 53 feet (2). The x-value of the y-intercept (C) is zero. That is the time the rock was thrown (6). (We start counting time from the time the rock was thrown.)

The high point on the graph is (x, y) = (4, 85). This is the vertex. The y-value of the vertex (F) tells us the maximum height of the rock is 85 ft (1). The x-value of the vertex (E) tells us the rock reached its maximum height at 4 seconds (5).

The x-axis, where y = 0, represents ground level.  The x-intercept (x, y) = (10.5, 0) is where the graph meets the x-axis. So, the y-value of the x-intercept (D) represents ground level (4). The x-value of the x-intercept (B) tells us the rock was in the air for 10.5 seconds (3).

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.

i believe the correct answer is b.
