I don’t understand fully

#

how do you think you'd approach this

#

looking at the lines, what types of lines do we have

sharp peak Oct 31, 2023, 9:30 PM

#

parallel and perpendicular

#

lines

#

yeah fair enough

#

could you come up with an equation for the line with the point A

sharp peak Oct 31, 2023, 10:38 PM

#

y = 10

#

now we need to calculate a gradient in order to form a second equation

#

if we already know L_1 is y=10

#

what gradient could we calculate next

#

sorry for not reply I had to go

#

A has the equation y= 0x+ 10. y=10

#

form an equation for the line BP
