Question

Are the lines parallel, perpendicular, or neither?

5x + 2y = 10
15x + 4y = -4

Answer 1

hmm hey :=))
i was about to leave.. well hmm
rewrite both equation in slope intercept form
y=mx+B
if the slopes are the same then parallel (parallel lines have same slope )
if the slopes are negative reciprocal ( exxample: a/b and the other slope -b/a) then perpendicular

Answer 2

can you solve for y ?? :=)) 5x+2y=10
btw y=mx+b
m is slope
