What is the equation of a line that is parallel to x=−5 and that passes through the point (1,4)
anastassius [24]
Answer: x = 1

The given line x = -5 is a vertical line through -5 on the x axis. Every point on this line has an x coordinate of -5. Similarly, the line x = 1 has all of its points with x coordinate of 1. One of those points is (1,4). Any vertical line has an undefined slope. Any two vertical lines are parallel to one another.

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.
