The slope-intercept form of a linear equation is y=mx + b, where x and y are
1coordinates of an ordered pair, m is the slope of the line, and b is where the line crosses
the y-axis.
which is an equivalent equation solved for the slope, m?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

Elizabeth claims that the fourth root of 2 can be expressed as 2^m since (2^m)^n = 2. find the values of m and n for the case where elizabeth's claim is true.

Serena is making an experiment. for that, she needs 20 grams of a 52% solution of salt. she has two large bottles of salt water: one with 40% and the other with 70% of salt in them. how much of each must she use to make the solution she needs? i am in need of
