Which table does NOT represent a linear function

topjm [15]

TABLE D does NOT represent a linear function

<h2>Explanation:</h2>

The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:

TABLE A, FIRST FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{8-5}{-1-0} \\ \\ m=-3$

TABLE C, SECOND FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{5-10}{-1-0} \\ \\ m=5$

TABLE C, THIRD FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{1-2}{-1-0} \\ \\ m=2$

TABLE D, FOURTH FIGURE:

It is not a linear function. It is likely this is a parabola that opens downward.

6 + 8/10x = 9/10x what is x?

WITCHER [35]

$\sf 6+ \frac{8}{10} x= \frac{9}{10} x$
Subtract $\frac{8}{10} x$ from both sides

$\sf 6+ \frac{8}{10} x - \frac{8}{10} x= \frac{9}{10} x- \frac{8}{10} x$

Simplify:
$\sf 6 = \frac{1}{10}x$

Multiply 10 on both sides:
$\sf 6 \times 10= \frac{1}{10}x \times 10$

Simplify
$\sf 60= x$

So your answer is x=60. :)
