Amarble paperweight shaped similar to a prism weighs 0.3 lb. how much does a similarly shaped marble paperweight weigh if its length, width, and height are doubled?

Maybe it's 2.4 lb. just a guess.

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!
