Question

helder_edwin · Answer

what is the slope of the line u r given?

anonymous · Answer

I have no clue sorry

helder_edwin · Answer

your equation has the form
$$ \large y=mx+b $$
here m is the slope and b is the y-intercept

helder_edwin · Answer

this means m=2 and the line passes through (0,4) right?

i have the 4 choices of a anwser but thats all tht came with that ?

anonymous · Answer

yea

helder_edwin · Answer

now when you have two lines say
$$ \large y=m_1x+b $$
$$ \large y=m_2x+c $$
for them to be perpendicular it must be
$$ \large m_1\cdot m_2=-1 $$
you have m1=2 find m2
