Question

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?

Answer 1

do you know how to do the substituion method, elimination, or graphing

Answer 2

not really

Answer 3

which one would you maybe have touched before

Answer 4

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.
