Question

What is the slope of the line that is perpendicular to the line whose equation is 2x + y = 4. -2 -2/3 1/2 2

Answer 1

ok so have you learned how to tell if two lines are perpendicular based on their slopes?

Answer 2

old question but will respond so this can be closed

equation: 2x + y = 4
subtract 2x from both sides:
y = -2x + 4

comparing this to y = mx + b to find your slope (m-value) and then take the opposite reciprocal
