Question

determine weather each pair of equations represents perpendicular lines. show work
y= -x+7
y -x =3

Answer 1

what can you tell me about conditions for two lines to be perpendicular to each other?

Answer 2

perpendicular means \[m_{1}=-\frac{1}{m_2}\]

Answer 3

y=mx+c
m=-1, m=1
so for perpndicular m1*m2= -1
here the condition satisfied

Answer 4

find the gradients of both the equations and if the gradient of one equation is the negative reciprocal of the other equations, then they are perpendicular

Answer 5

first line has slope -1, second has slope 1, so perpendicular.

Answer 6

equation*
