Lizzy is tiling a kitchen floor for the first time. She had a tough time at first and placed only 6 tiles the first day. She started to go faster and by the end of day 4 she had placed 36 tiles. She w?

Lizzy's tiling progress can be modeled by a linear equation in slope-intercept form, y = mx + b, where y represents the number of tiles placed and x represents the number of days. By using the points (1, 6) and (4, 36), we can calculate the slope (m) as (36-6)/(4-1) = 30/3 = 10. Substituting one of the points into the equation, we can solve for the y-intercept (b) as 6 = 10(1) + b, giving b = -4. Therefore, the equation representing Lizzy's progress is y = 10x - 4.
