Question

All points with coordinates (x, y) that are equidistant from the points (1, 3) and (7, 11) lie
along a single line. When the equation of the line is written in the form y = mx + b, what is
the value of b?

Answer 1

find the midpoint of (7,11) and(1.3)

Answer 2

y = mx + b is the slope intercept form, which b representing the y intercept. The y intercept is where x = 0 or (0,y).

Answer 3

Do you have the program Geogebra?

Answer 4

No and Thank you so much chaotic_butterflies

Answer 5

It's nothing hon! Alrighty, well I'm going to give you the link to the program, it's really helpful to graph your problem so you can get an image in your head of it. http://www.geogebra.org/cms/
I recommend you download that for help in the future. Meanwhile, I already graphed your problem with the program, so I'll attach that image in just a sec!

Answer 6

The answer is actually 10 but it's okay I still give you credit for trying.

Answer 7

Oh, did you know how to get the answer?

Answer 8

You're answer said 0 but the graph represents that x=10.

Answer 9

That's not my answer... I was showing you what you should be looking for.

Answer 10

when x=0, that means that there will be a value directly on the y axis. However, your answer doesn't line up with the information that you gave me.

Answer 11

Is there something else that you left out from the question?
