y = a + bx. where y is the dependent variable and x is the independent variable. In this case, the slope is equal to b and a is the intercept. When plotted on a graph, y is determined by the value of x. Regression equations are charted as a line and are important in calculating economic data and stock prices.
I just took a prom dress to be dry cleaned and they are charging $25.00.
PROM GOWN: The cost of your gown is completely up to you, and your budget. You may stitch one up yourself, go to a âone-of-a-kindâ boutique, visit a thrift store, or hit a department store. Most prom dresses cost between $100 and $400.ROM TICKETS: $20 to $250 depending on the location. If your prom is being held in a fancy hotel, ballroom, or a night club it may be more costly than if it is being held in your school gymnasium.
