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

1/2

Step-by-step explanation:

2x+y =4

Lets solve for y so the equation is in slope intercept form

Subtract 2x from each side

2x-2x+y = -2x+4

y = -2x+4

The slope is-2

When we want a perpendicular line, the slope is the negative reciprocal

-(1/-2)

+ 1/2

The slope of the new line is 1/2

i dont know

step-by-step explanation:

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
