Answer:

y = -2x + 8

Step-by-step explanation:

When two points are given, the equation of the line passing through the points is given by:

$\frac{y - y_1}{y_2 - y_1} = \frac{x - x_1}{x_2 - x_1}$

where: $(x_1,y_1)$ and $(x_2,y_2)$ are the two points passing through the line.

Here, $(x_1,y_1) = (2,4)$ and $(x_2, y_2) = (3,2)$ .

Substituting in the formula, we have:

$\frac{y - 4}{2 - 4} = \frac{x - 2}{3 - 2}$

⇒ $\frac{y - 4}{-2} = \frac{x - 2}{1}$

⇒ y - 4 = -2x + 4

⇒ y = -2x + 8 is the required equation of the line.
