Question

Module Knowledge Check Find the slope of the line passing through the points (-5,3) and (7,9).

Answer 1

To solve this problem, use the equation slope= y₂ - y₁/ x₂ - x₁

where y₂ and x₂ are a set of coordinates, and y₁ and x₁ are another pair of coordinates.

In the problem, you have been given 2 coordinates: points (-5,3) and (7,9)

Plug in these points into the equation: slope =
`(9-3)/(7-(-5))`

Now solve!

9-3=6

7- (-5)= 7+5= 12

`(6)/(12)` = 1/2

1/2 is the slope of the line
