Answer:
m = 2
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Perpendicular lines have a negative reciprocal slope.
Step-by-step explanation:
Step 1: Define
y = -1/2x + 4
Step 2: Identify
Slope m = -1/2
Step 3: Solve
Reciprocate and multiply by negative
m = 2
