Answer from: Rosy1234Locks

Answer-

Only the first table represents a linear function.

Solution-

In order to be in linear function, the graph of the function must be a straight line.

Plotting the graph, by taking the data points from the given table and then plotting in the cartesian coordinates system, several graphs are generated. Among them only the 1st table, yields a straight line with a constant slope.

So, the 1st table represents a linear function, where x and y are in direct proportion with positive slope, hence when x increases, so does the y.

Which table represents a linear function?

Answer from: emmahuber980

The table A is the correct option.

Further explanation:

The linear equation with slope m and y-intercept c is given as follows.

$\boxed{y = mx + c}$

Explanation:

Plot the points $\left( {1,\dfrac{1}{2}}\right),\left( {2,1} \right),\left( {3,1\dfrac{1}{2}} \right)$ and $\left( {4,2} \right)$ from the table 1

The graph of table 1 shows the linear function.

Plot the points $\left( {1,1} \right),\left( {2,\dfrac{1}{2}} \right),\left( {3,\dfrac{1}{3}} \right)$ and $\left( {4,2} \right)$ from the table 2.

The graph of table 2 shows that the function is not linear.

Plot the points $\left( {1,7} \right), \left( {2,9} \right), \left( {3,13} \right)$ and $\left( {4,21} \right)$ from the table 3.

The graph of table 3 shows that the function is not linear.

Plot the points $\left( {1,0} \right), \left( {2,6} \right), \left( {3,16} \right)$ and $\left( {4,30} \right)$ from the table 3.

The graph of table 3 shows that the function is not linear.

The table A is the correct option.
