What is the equation of the line?

use y = mx+b

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 2) ← 2 points on the line

m = = -

Note the line crosses the y- axis at (0, 4) ⇒ c = 4

y = - x + 4 ← equation of line
