Slope-Intercept Form 2.08

x y in weeks The baby was 20 inches long when it was born and is growing at a rate of 1 inch every 4 weeks. Determine the slope (rate of change) 1 4

Vocabulary  Slope:  The rate of change of a line, written as a fraction  Initial Value:  The y-value when x = 0  Also called the starting point and the y-intercept

Slope-Intercept form of a line: y = mx + b Slope Rate of change Initial Value Y-Intercept Starting point

Steps:  1) Identify the slope of the line.  2) Identify the y-intercept (initial value, starting point).  3) Plug these values into the Slope-Intercept equation for m and b.

Examples: 3 -2

Examples:

Practice!  Complete the back carefully.
