Question

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) ?

Answer 1

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

Answer 2

goes first

Answer 3

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)
