Can you help me?

I have this question:
Find the equation of the line given the following information:
m=UD, x=3.
And I have to find the equation.

Then it says:
Identify the slope and y intercept from the following equations:
x=5, m=___, b=___
I also have to graph it.

But I don't understand how to do this if the slope is UD!
Help me!

equation is

y = (UD)x + b

Until you reveal more information about this mysterious UD , that's all I can give you.

UD is undefined...

Ok, then ....

If the slope is undefined, you have a vertical line.
All vertical lines can be defined only by their x value.
since x = 3
the equation of your line is x = 3

Furthermore, if the slope is undefined, that is, if the line is vertical it CANNOT be written in the form
y = mx + b
A vertical line cannot have a y-intercept, unless it is the y-axis itself, namely x = 0

if x = 5, that becomes your equation of that vertical line.
To graph it, use (5,0) on the x-axis, then draw a vertical line.

Oh Thanks so much for your help!

But can I just ask, do the two equation have anything to do with each other? And don't I have to times both sides by 5/3 to make it equal?

Of course, I'll be happy to help you!

Let's start with the first question: finding the equation of a line given the information m=UD and x=3.

To find the equation of a line, we usually use the slope-intercept form, y = mx + b, where m represents the slope and b represents the y-intercept.

In this case, we are given the slope, m=UD. However, "UD" is not a valid numeric value for slope. If you have any additional information or if there is a mistake in the question, please provide it so that I can assist you further.

Moving on to the second question about identifying the slope and y-intercept from the equation x=5.

The equation x=5 is not in the slope-intercept form, y = mx + b. Instead, it represents a vertical line passing through the x-coordinate 5. Vertical lines have undefined slopes because they do not have a change in y corresponding to a change in x, as all points on the line have the same x-coordinate.

Therefore, for the equation x=5, the slope (m) is undefined or "UD," and there is no y-intercept (b) because the line does not intersect the y-axis.

To graph the equation x=5, you simply need to draw a vertical line passing through the x-coordinate 5 on the x-axis.

I hope this clarifies the confusion! If you have any more questions, feel free to ask.
