y=mx+b is slope intercept form where `m` is slope and `b` is y-intercept

How'd you get it though?

i didn't get anything it's the original equation for slope intercept form

OH sorry! Could you help me solve ABCD for that problem? and explain how you got the answers

okay!

so what's the slope of line J ??

Y=-4+2x?

just slope

like i said y=mx+b m is slope which is always with x variable

so 2?

yes right

so it's the same?

yes right

SO that would be by anwser for A?

yes what about B ?

The same because anything that's parallell is the same

yes right!

OK:)))

\[\huge\rm y=2x+b\] passes through (3,7)
so replace (x,y) with (3,7) and solve for b

7+2*3+b?

if you mean 7 `=` 2(3)+b then yes now solve for b

1?

yes right
so b=1 now you can replace b with one in the original equation

7=2(3)+1

well we need in slope intercept form so keep the x and y variables
y=2x+1

thank you

i've to go will be back

y=-4+2x

ok how long?

oh well got few mints

oh good!

so what's the perpendicular slope for line h ?

So I had it right?

no

-4+2x=y

remember : parallel lines `same slope `
perpendicular slopes `negative reciprocal`

ok

what's the slope of line j ?

-4+2x=j

why are u keep posting that equation ?
j=2x `+` 4

ok

what's the `slope`( not the equation) of line J ?

2

yes right so slope of line h would be negative reciprocal of 2

you prob think im stupid but are we on C or D?

for which part they are asking `perpendicular ` equation ? :=)

D:)

yes so ofc D

-2

what's the reciprocal of 2 ?
it's same as 2/1

1/2

or 1

no 1/2 is right so it would be -1/2

ok

now replace m with -1/2 and substitute (x,y) for given order to find b

help

what's the original equation of slope intercept ?

for **

j=2x=4

+4

-1/2+8+10

hmm y=mx+b
y value should at left side

just like u did for part C

10=-1/2(8)

yes right solve for b 10=-1/2(8)+b

gtg

ok

b=21/2=10.500

hmm no \[10=-\frac{ 1 }{ 2 }(8)+b\] you can divide 8/2

it shouldn't be decimal
