Which of the following equations graphs as a vertical parallel to the y-axis

You forgot to add the options, however, I will tell you the concept of the problem and you can then choose the correct choice from the ones you have.

First, the slope of a vertical line is 1/infinity which is undefined.
Second, for a vertical line, you can notice that the value of the x is constant along the line.
Third, the y-axis has an equation x=0. Any line parallel to the y-axis will be located at a distance d from the y (d can be positive or negative depending on whether the line is to the left or to the right of the y-axis). Therefore, the equation of any line parallel to the y-axis would be x=0+d

Based on the above, the correct choice would be the equation in the form of:
x = constant

Just divide the x axis (the top) by 2 or multiply the y axis (the bottom) by 2

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
