Answer:
The slope of the line passing through the points (-3,5) and (21,5) is 0
Step-by-step explanation:
The slope of a line passing through the points (x₁, y₁) and (x₂, y₂) is calculated as:
For the line passimng through the points (-3,5) and (21,5):
Substitute x₁ = -3, y₁ = 5, x₂ = 21, y₂ = 5 into the slope formula above
Therefore, the slope of the line passing through the points (-3,5) and (21,5) is 0
