The values of the slope of a line is a measure of the amount of change in the dependent (vertical) variable which accompanies a unit change in the ndependent (horizontal) variable.

How do you interpret the slope and y intercept in a real world case?
A positive slope is a slope that is increasing when read from left to right. To be increasing, means that as the x values are increasing, so are the y values as the graph is read from left to right.
In math, the slope of a line represents its steepness. It is the change in y values over the change in the values of x, or rise over run.
Select two distinct values of X, designated X1 and X2, from the table, read the corresponding values Y1 and Y2 from the table, and calculate the slope from the formula: slope = (Y2 - Y1)/(X2 - X1)
slope is the steepness of a line, it is defined by the change in the y values divided by the change in the x values of any two points on a line (x1, y1) and (x2, y2) slope = (y1 - y2)/(x1 - x2)
