Question 3, thanks for the help :)

The slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

Step-by-step explanation:

Given the points

Here:

(x₁, y₁) = (1, 2)

(x₂, y₂) = (3, 8)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

               =  [8 - 2] / [3 - 1]

               = 6 / 2

               = 3

Thus, the slope of the line passing through (1, 2)  and (3, 8)  is:

Slope = 3

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
