The weight of 10 identical samples of a substance is 0.001 pound what is the weight of 100 samples?

0.01 pound, assuming the 100 samples are also all identical.

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!

You need to do x2-x1,y2-y1 and divide it by 2 and you should get (1,-3)
