If y=2x-3 were changed to y=2x+5 , how would the graph of new function compare with the original?

The new graph would have the same slope (2) as the original one,
but its y-intercept would be [ 5 - (-3) ] = 8 higher.

The new straight line would be parallel to the original straight line,
and they would be 8 units apart everywhere.

Where is the graph function?

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.
