for part II, the slope can be simplified to 3
OpenStudy (studygurl14):
For part III, remember that parallel lines have equal slopes
OpenStudy (anonymous):
hmmm /:
OpenStudy (studygurl14):
if the slope of teh first equation in 3, then the slope of the second equation must also be 3
OpenStudy (anonymous):
the choices are A) x^2 = 10+36/10y^2
B) x^2= 100+36/10y^2
C) x^2=100+36y^2
D) x^2 =10+6/10y^2

Can you help me set up the equation :p
OpenStudy (studygurl14):
the only difference is the b-value in the equation y= mx + b, aka the y-intercept
OpenStudy (studygurl14):
slope-intercept form:
y = 3x + b
with point (4,2)
OpenStudy (studygurl14):
remember: (x,y)
plug in the values of x and y into the equation above^
OpenStudy (anonymous):
2 = 3(4) + b ?

correct. next, solve for b
OpenStudy (anonymous):
2 = 12 + b
-12 -12
-10 = b ?
OpenStudy (studygurl14):
correct
OpenStudy (studygurl14):
now, just put that back into the equation
y= 3x + b
OpenStudy (anonymous):
y = 3x - 10 ?
