Question

can someone please tell me how to find the slope of a graph?

Answer 1

what kind of graph?
a line or a graph of some equation that curves?

Answer 2

a line graph

Answer 3

I assume you are given a picture, or at least two points on the graph?

Answer 4

yes something like this

Answer 5

I see 5 points on that graph
pick any two of those points (it doesn't matter which) and list out the coordinates like so:
(x,y)
write that out and I will tell you where to go from there

Answer 6

:(
can u do it let me see it

Answer 7

how do i find coordinates?

Answer 8

I will give you one:
at x=1, notice that if you follow the blue dot above it to the left you get the y-coordinate which is 10

Answer 9

so that point on the upper-right corner is (1,10)

Answer 10

that means that when x=1, y=10
find another point using the same method

Answer 11

x=-2,y=5 ?

Answer 12

careful, I think it's x=-2,y=-5
notice we are below the x-axis, and whenever that is the case y is negative

Answer 13

so now we have two points
let's call them (x1,y1) and (x2,y2)
it does not matter which is which
(-2,-5) and (1,10) are our points

Answer 14

given two points on a line, (x1,y1) and (x2,y2) the slope is given by\[slope={y_2-y_1\over x_2-x_1}\]so just plug in the numbers into the formula and you get the slope
