If the equation of a line is 4x+4y=1 and the equation of a second line is x+y =-8. Which of the following is true? A. The lines are perpendicular
B. The lines are parallel
C. Both lines intersect at point (0,-8)
D. The lines share the same x-intercept

Respuesta :

Convert the equations to slope/intercept form:-

4x + 4y = 1

4y = -4x + 1

y = -1x + 1/4     The slope of this line is -1

x + y = -8

y = -1x - 8  This also has a slope of -1

So B is true.  The lines are parallel.
