Answer:
<h2>
y = -¹/₂
x + 4 </h2>
Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -¹/₂
(2, 3) ⇒ x₀ = 2, y₀ = 3
The point-slope form of the equation:
y - 3 = -¹/₂
(x - 2)
So:
y - 3 = -¹/₂
x + 1 {add 3 to both sides}
y = -¹/₂
x + 4 ← the slope-intercept form of the equation
