Question

Determine whether the graph is parallel perpendicular, or neither. explain
2x - 5y = 0
y+3 = 5/2 x

Answer 1

Perpendicular as the slopes are negative/inverse.

Answer 2

yup

Answer 3

solve both for y
to put in y=mx+b form

if both m's =, then the lines are parellel
if m1*m2=-1, then lines are perpendicular

Answer 4

negative reciprocals is better term
