a] lhe tollowing linear equation describes the relationship between y, the number ot property crimes per week in a particular urban district, and x, the number at police otlicers on daily street patrol: 3x V _+_=3 10 5 Rewrite the equation in slopeintercept form and nd the slope. Enter the value as a decimal to the nearest tenth: m=:|. How many crimes occur if no police are on patrol? Enter the value as an integer: :|_ How many patrol police are required to reduce the crime rate to zero? Enter the value as an integer: :I. b) Find a Linear Model After a spring of rapid melt and rain, the water depth in a river reached a peak value. Then the depth began to drop. After 1" days the water depth was 3 m and after 12 days the water depth was 2 m Assuming the water depth talls at a constant rate, nd a linear function which describes the water depth, y, as a function of time in days after beginning to drop, x. The model should be in the form of y = mx + b {slopeintercept form). Enter the value ofm as a decimal to the nearest tenth: m=|:|. What was the peak water depth? Enter this value as a decimal to the nearest tenth: b=1:|
