Slope from (0, 5) to (3, 8)
Calculate the slope of the line passing through points (0, 5) and (3, 8).
Answer:
Slope m = m = 1
Step-by-Step Solution
Step 1
Slope Formula
The slope of a line through two points is:
m = (y₂ - y₁)/(x₂ - x₁)
This represents 'rise over run' or the rate of change
m = (y₂ - y₁)/(x₂ - x₁)
Step 2
Identify the Points
Point 1: (x₁, y₁) = (0, 5)
Point 2: (x₂, y₂) = (3, 8)
P₁(0, 5), P₂(3, 8)
Step 3
Calculate Rise and Run
Rise = y₂ - y₁ = 8 - 5 = 3
Run = x₂ - x₁ = 3 - 0 = 3
Rise = 3, Run = 3
Step 4
Calculate Slope
m = rise/run = 3/3
m = 1
Step 5
Interpretation
Positive slope: line rises from left to right
For every 3 units of horizontal change, there is 3 units of vertical change
Angle with x-axis: 45.00°
Slope = 1
Step 6
