Answer: x + 7y = 12

Explanation:


The question is: "Indicate in standard form the equation of the line passing through the given points. E(-2, 2), F(5, 1)"


1) The standard form of the equation of the line passing through two points is:

Ax + By = C

2) You can find the equation of al line given two points in a two stages process:

i) Find the slope:

slope = m = [y₂ - y₁] / [ x₂ - x₁] = [1 - 2] / [5 - (-2) ] = - 1 / 7

ii) set the point slope equation:

y - y₁ = m [x - x₁]

y - 1 = (-1/7) (x - 5) ⇒ 7 ( y - 1) = - (x - 5)

⇒ 7y - 7 = - x + 5 ⇒ x + 7y = 5 + 7

⇒ x + 7y = 12
