c. graph c.

step-by-step explanation:

a decrease in a graph is a graph that goes down to the right.

both the first and third graphs start by going down to the right, so they both start by decreasing.

an increase is shown with a graph that goes up to the right. the third graph goes up to the right after it reaches the y-axis. it does cross the y-axis at (0, -7)

answer: c. graph c.

Answer from: LuxTheGirl5214

answer: c. graph c

step-by-step explanation: its asking for the one that decreases which it cannot be graph b because it increases first. then it ask for which is the one that after it deceased it crosses (0, -7) and then increases. it can't be graph a because it decreases and and stays on each straight line while graph c crosses (0, -7) and then increases.

Answer from: Quest

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!

$4/2 = 2\\7/3.5=2\\8/4=2\\10/5=2$

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:

$y=\frac{x}{2}$

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.
