Samuel wrote the equation in slope-intercept form using two points of a linear function represented in a table. Analyze the steps Samuel used to write the equation of the line in slope-intercept form. A 2-column table with 4 rows. Column 1 is labeled x with entries negative 7, negative 5, negative 3, negative 1. Column 2 is labeled y with entries 13, 5, negative 3, negative 11. 1: m = StartFraction negative 3 minus 5 Over (negative 3) minus (negative 5) EndFraction = StartFraction negative 8 Over 2 EndFraction = negative 4. 2: 5 = negative 4 (negative 5) + b. 5 = 20 + b. b = negative 15. 3: y = negative 15 x minus 4.
