Question

I need help!

1.Find the distance between the points: (–6, 7) and (–1, –5).

2.The midpoint of A (-4, 2) and B(8, 5) is

3.Indicate the equation of the line through (2, -4) and having slope of 3/5.

4.Find the coordinates of the midpoint of the segment connecting points (–3, –6) and (2, 5).

5.Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5).

Answer 1

okay so these are super easy do you know any of the formulas ?

Answer 2

The only equation I can remember is y1-y2/x1-x2

Answer 3

Use the distance formula for number 1
the midpoint formula for number 2
point-slope for number 3
midpoint number 4
midpoint and point-slope for number 5

Answer 4

I don't remember them

Answer 5

1.)
(x2-x1)2+(y2−y1)2

2.)
x1+x22?+y1+y22?

3.) y-y1=M(x-y1)
4.) use formula for #2
5.) use formula for #2 & #3

Answer 6

I'd strongly suggest that you look up the appropriate formulas. For example, for the first problem, you could Google "distance formula."

The formula you remember is for the slope of a straight line through two given points.

Answer 7

Please, would you now Google "distance formula" and copy down the formula discussed in some of the search results?

Answer 8

then you'll be well on your way to solving Problem #1.

Answer 9

Three people have given you clues regarding what to search for in Google. Hope you'll take their advice. the more you're involved in this problem solving, the better y ou're likely to understand what you're doing here (and to remember the formulas!!).
