## anonymous551 2 years ago Estimating slope of a graph without a grid? Slope of (0,0) to (3,6) ? Slope of (0,2) to (6,3) ? Slope of (1,0) to (6,6) ?

1. naynaylala

first number the sides with ruler(centimeters/inches depending on problem)and you plot in coordinates and remember that x horizontal

2. naynaylala

goes first

3. asnaseer

you do not need to graph anything in order to find the slope between two given points. the slope is just the change in y divided by the change in x. e.g. the slope of a line between (x1,y1) and (x2,y2) would be: slope = (y2 - y1)/(x2 - x1)

5. precal

use the slope formula, as told by asnaseer

7. satellite73

right 3 units, up six units, slope is $$\frac{6}{3}=2$$

8. precal

satellite is doing rise over run, another way to do slopes.
