Question

How can you use proportional and nonproportional linear relationships to solve problems

Answer 1

To solve problems using proportional linear relationships, we can use the formula
`y=kx`, where y is the dependent variable, x is the independent variable, and k is the constant of proportionality.

To solve problems using nonproportional linear relationships, we can use the slope-intercept form of a linear equation, which is
`y=mx+b`, where m is the slope and b is the y-intercept.
