Question

Sally collected 34.9 pounds of cans to recycle and plans to collect 3.3 more pounds each week. Write an equation in slope-intercept form where x represents the number of weeks Sally has been recycling cans, and y represents the total amount recycled.

Answer 1

y = 3.3x + 34.9

Explanation:

the slope-intercept form is y = mx + b.

y = total pounds of cans accumulated

m (slope) = pounds of cans collected each week (3.3)

x = # of weeks after sally starts collecting

b (y-intercept) = initial pounds of cans collected (34.9)

so:

y = (pounds per week)(# of weeks) + initial weight

y = 3.3x + 34.9
