Is the line through points p(-7,2) and q(7,-6) parallel to the line through points r9-1,-5) and s(-3,-1)? explain a. no; one lin has zero slope the other has no slope yes; the lines are both vertical yes; the lines have equal slopes no; the lines have unequal slopes

No : the lines have unequal slopes

Parallel lines have equal slopes

calculate the slope( m) of each line using the gradient formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, 2) and (x₂, y₂ ) = (7, - 6 )

m = = = -

slope of other line using

(x₁, y₁ ) = (- 1, - 5 ) and (x₂, y₂ ) = (- 3, - 1 )

m = = = - 2

lines are not parallel since slopes are unequal

10+4√2 is the answer. i dont have the time to explain.
