Question

How do you find the slope of the line through (-4,-5) and (4,5)?

Answer 1

The slope of a line between two points is the difference between the `y` coordinates divided by the difference between the `x` coordinates

Given the points `(-4,-5)` and `(4,5)`

slope `= (Delta y)/(Delta x) = (5-(-5))/(4-(-4)) = 10/8 = 5/4`
