Line QR goes through points Q(0, 1) and R(2, 7). Which equation represents line QR? a. y – 1 = 6x b. y – 1 = 3x c. y – 7 = 2x – 6 d. y – 7 = x – 2

@Musicdude

OpenStudy (anonymous):

ok do you know your Point-Slope formula??

OpenStudy (anonymous):

yes @Musicdude

OpenStudy (anonymous):

ok what is you x1 and y1?

OpenStudy (anonymous):

and what is your x2 and y2?

OpenStudy (anonymous):

x1 is 0 y1 is 1 x2 is 2 y2 is 7 @Musicdude

OpenStudy (anonymous):

ok cool now just plug that into your formula and what do you get??

OpenStudy (anonymous):

c? @Musicdude

OpenStudy (anonymous):

not quite

OpenStudy (anonymous):

d? @Musicdude

OpenStudy (anonymous):

ehh

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

ok lets think about it another way

OpenStudy (anonymous):

okay b or a? @Musicdude

OpenStudy (anonymous):

lol yes

OpenStudy (anonymous):

but you have to try and get the answer

OpenStudy (anonymous):

b? @Musicdude

OpenStudy (anonymous):

so you know y=mx+b?

OpenStudy (anonymous):

yes @Musicdude

OpenStudy (anonymous):

ok so b is when x is 0 does that sound familiar

OpenStudy (anonymous):

yeah @Musicdude

OpenStudy (anonymous):

alright in this what is your b?

OpenStudy (anonymous):

|dw:1444453174479:dw|

OpenStudy (anonymous):

0 @Musicdude

OpenStudy (anonymous):

no x equals 0 so your b is 1

OpenStudy (anonymous):

b is Y-intercept

OpenStudy (anonymous):

so that means the answer is a @Musicdude

OpenStudy (anonymous):

no

OpenStudy (anonymous):

then its b @Musicdude

OpenStudy (anonymous):

i meant b in the equation y=mx+b not the answer choice

OpenStudy (anonymous):

yea it is but you get why?

OpenStudy (anonymous):

yeah i get it i got a little confused but i think i got it @Musicdude

OpenStudy (anonymous):

ok cool goodnight :)
