50POINTS HELP ASAP I ALREADY HAE HIS OVER DUE
1. Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days. Peter’s Deliveries
(a) What is the equation of the line, first written in point-slope form and then written in slope-intercept form? Show how you determined the equation. (b) Based on the linear model, predict how long it initially took Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences
Answer from: kenzielema12
y - 12 = -3 (x - 6)
y = -3x +6
6 minutes
The delivery times decreased by 3 minutes each day
Step-by-step explanation:
Point Slope:
Let's pick a point first (6,12)
The Slope of the line is -3
y - y1 = m (x - x1)
y - 12 = -3 (x - 6)
Slope-intercept:
The y-intercept is not shown on the graph but we can turn the point slope form of the equation to slope-intercept
y - 12 = -3x + 18
y = -3x +6
y-intercept:
y = mx + b
y = -3x + 6
m = 6
6 minutes
Slope:
we already know the slope is 3
The delivery times decreased by 3 minutes each day

Answer from: Quest
24
step-by-step explanation:
the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is
30% × 80 = 0.30 × 80 = 24
