find the slope between points 5,-3) 7,3?

Question

i would make 5 x1, -3 y1,7 x2,3 y2..than i would add them i get 6/12 reduce it to 1/3.. y=mx+b y is -3 m is 1/3 x is 5 +b... is that correct?

Answer 1

You don't add them together to find the slope.

Slope = change of y/change of x or:
(-3-3)/(5-7)
-6/-2 = 3

The slope is 3.

Now to finish the equation, you can plug an ordered pair into y = mx + b to find the y-intercept
3 = 3(7) + b
3 = 21 + b
b = -18

Final equation:
y = 3x - 18

Answer 2

Wow! When you reduce 6/12 and get 1/3, I wondor whether I can help.

From your question I'm guessing you're wanting to get the slope of a line thru these 2 points so you can write the equation of the line.

slope(m) = change-in-y / change-in-x or if you must be formula tied

m = (y1 - y2) / (x1 - x2) Personally I cringe at tying myself to a formula, BUT if you must, then fill it in this way: Draw your fraction bar, then put in x1, y1 first and stick a minus sign beside each term; then stick in x2, y2 to finish the fraction that you must simplify. Slope(m) = 3.

You can compute the y intercept (b) by plugging in either point, along with m = 3 into y = mx + b (and determine
b = -18 to get the line y = 3x - 18

OR

You could write y - y1 = 3(x - x1) and claim that's the line thru the 2 points. (It is also obvious that you could claim y - y2 = 3(x - x2) is the line. All are equivalent.
(It's worth noting that these 2 line forms are nothing more
than a juggling of the slope definition given above.)

Answer 3

once you're requested to locate the slope of two ordered pairs you want to apply the slope formula m = y2-y1/x2-x1 <---------Slope formula keep in innovations (x, y) (-3, 4),(5, a million) m = a million - 4/5 - (-3) m = a million - 4/5+3 m = -3/8 Now utilizing y = mx + b we may be able to remedy for b utilizing the slope and both ordered pair a million = -3/8(5) + b a million = -15/8 + b a million + 15/8 = b a million/a million + 15/8 = b 8/8 + 15/8 = b 23/8 = b placed all of it at the same time: y = -3/8x + 23/8 <-------------answer 2d part of the concern: to locate the area between those 2 factors we want to apply the area formula d = ?[(x2 - x1)^2 + (y2 - y1)^2] <---------distance formula utilizing substitution we may be able to remedy this concern d = ?[(5 - (-3))^2 + (a million - 4)^2] d = ?[(5 + 3)^2 + (a million - 4)^2] d = ?[(8)^2 + (-3)^2] d = ?(sixty 4 + 9) d =?(seventy 3) d ? 8.fifty 4 <----------answer advantages

Answer 4

The slope of the line that runs through of (5,-3) and (7,3) is 3.

Using the slope rule of lines:
(y1-y2) over (x1-x2)

(3 - -3) over (7 - 5) = 6/2 = m = 3.

Answer 5

m = (y2- y1)/(x2 - x1) = (3 -(-3)) / (7 -5) = 6/2 = 3


By the way, you show 6/12 reduces to 1/3; actually, it reduces to 1/2

Answer 6

im sorry, i don't follow what you're doing,

but the slope is change in ys over change in xs,

so 3 - (-3) over 7-5

which get 6/2, or 3.
