Answer:hmm I don’t fully understand what you mean because there is no bottom of the number line it started at zero so all you have to do is fill the line in.

Answer:

  get a clue from the problem statement, figure out what you need to help you solve the problem

Step-by-step explanation:

You need to read and understand the entire problem. Different parts of it give you different clues as to how to arrive at appropriate number lines.

Here are some of them:

  1. groups of 3 red cups and 2 blue cups are circled, telling you that 3 red corresponds to 2 blue, and that this combination is one batch
  2. each number line has 4 tick marks
  3. part b asks for the number of blue associated with 12 red (so you might want to make sure the numbers on the red number line go that high)
  4. part c asks for the number of reds associated with 6 blues (so you might want to make sure the blue numbers go that high)
  5. the questions are about "batches", so the tick marks may want to correspond to batches in some way

The double number line is a tool, just as any diagram is a tool to help you solve a problem. You choose the way you draw it so that it is of help to you in answering the questions asked.

10]The graph of a function is a line that passes through the coordinates (2, 11) and (8. 14).Which is an equation in terms of x
aksik [14]

We know that the graph of a function is a line that passes through the coordinates (2, 11) and (8, 14) and we must find the equation for the line.

1. We must use the next formula to find the slope

m=\frac{y_2-y_1}{x_2-x_1}

Where (x1, y1) and (x2, y2) are the points.

Now, replacing the points in the formula for the slope

m=\frac{14-11}{8-2}=\frac{3}{6}=\frac{1}{2}

2. We must replace the slope and one of the points in the next formula

y-y_1=m(x-x_1)

Now, replacing the slope and the point (2, 11)

\begin{gathered} y-11=\frac{1}{2}(x-2) \\  \end{gathered}

3. We must delete the parenthesis and solve the equation for y

\begin{gathered} y-11=\frac{1}{2}x-\frac{1}{2}\cdot2 \\ y-11=\frac{1}{2}x-1 \\ y=\frac{1}{2}x-1+11 \\ y=\frac{1}{2}x+10 \end{gathered}

ANSWER:

y=\frac{1}{2}x+10
