Which of the equations best represents the ordered pairs in the table? x 1 2 3 4 y 7 12 17 22 y = 5x + 5 y = 7x + 5 y = 7x + 22 y = 5x + 2

OpenStudy (godlovesme):

in what pattern is the y increasing as u go one unit for the x @theviolentredhead

OpenStudy (anonymous):

5

OpenStudy (anonymous):

for y

OpenStudy (godlovesme):

great that is ur slope :) r u familiar with the slope-intercept form?

OpenStudy (anonymous):

yes!

OpenStudy (godlovesme):

y=mx+b so far we have y=5x+b y-intercept is the value of y when x is 0 right?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so its either +2 or +5?

OpenStudy (godlovesme):

its +2 5 is our slope so whats the overall equation?

OpenStudy (anonymous):

y = 5x + 2?

OpenStudy (godlovesme):

:D yep

OpenStudy (anonymous):

thank yououoou:)

OpenStudy (godlovesme):
