How do you find the slope?

Question

ofind the slope of the line that passes through each pair of points:

(-2,3) and (4,9)

Answer 1

Slope or rate of change is found by the equations

m=(y2-y1)/(x2-x1)

where m represents slope


(This means the same as rise over run.)

The two ordered pairs you gave me are in the form (x,y). First let one set be (x1,y1) and the other be (x2,y2).

x1=-2
y1=3

x2=4
y2=9

So plug these numbers into the formula

m= (y2-y1)/(x2-x1)

m= (9-3)/(4-(-2)

m= 6/6

m= 1

The slope of this line is 1.

Answer 2

It is the difference in the x coordinates divided by the difference in the y coordinates.

slope= (-2-4)/(3-9)=-6/-6=1

Answer 3

50% or 45 degrees in surveying or 1.00 in mathematics.

If you plotted the 2 points on a graph and joined them together the line would go 6 units along (difference between -2 and 4) and it would go 6 units up (diff between 3 and 9), the angle is therefore 45 degrees (or 50%).

To give slope as a mathematical answer you divide x (along) by y (up). In this case 6 divided by 6 = 1.00.

Answer 4

if u draw it out it wud be rise over run
if u do it on paper by math it wud be the change of y over the change of x

Answer 5

(y2-y1)/(x2-x1)=m
(9-3)/(4--2)=m
(6)/(6)=m
m=1

Answer 6

y=mx+b
