Question

A steel beam can be cut to different lengths for a project. Assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship? (10 points!!!)

Answer 1

Answer:

the weight of the steel beam and steel beam length

let y be weight and x be length of it

y=ax

where a is the constant

we can find it if we have two sets of values of y and x
