Write the equation of the line that has an undefined slope and passes through the point (4, 7). user: what is the slope of a line that is parallel to the x-axis? user: what is the slope of the line that passes through the points (-3, 5) and (1, 7)? user: which of the following equations is the translation 2 units left of the graph of y = |x|?

1.

Explanation:

as we know that equation of straight line passing through a fixed point and having undefined slope is given as

here we have

so we will have

2.

slope = ZERO

Explanation:

Slope of the straight line is defined as the tangent of the angle made by the line with respect to x axis

here we need to find the slope of a straight line parallel to x axis so the angle is ZERO degree

hence the slope will be given as

3.

Explanation:

Slope of a straight line passing through two different points is given as

here we will have

4.

here x' = any positive number

Explanation:

If we translate the graph 2 units left of the given position so we can say that we have shifted the graph above from its given position.

So we will have

here x' = any positive number
