Mass Write whether you would use grams or kilograms to measure the mass of each object. Safety pin 2 Motorcycle Orange Circle the measurement that is more likely. Tennis ball 55 grams or 55 kilograms Savvas Learning Company Cat 5 kilograms or 50 kilograms Bunch of grapes 1 gram or 1 kilogram​

9/12 is the answer because 3/4 times 3 each is 9/12

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.

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!
