ok hello
OpenStudy (anonymous):
Hi
OpenStudy (anonymous):
What is the slope of a line parallel to the line with equation 2x - 5y = 9?

OpenStudy (danjs):
well parallel means that it will have the same slope
OpenStudy (anonymous):
A. 2/5
B. -2/5
C. -5/2
D. -9/5
OpenStudy (danjs):
change that given equation into ,, y = mx + b form first
OpenStudy (anonymous):
m is the slope right?
OpenStudy (danjs):
2x = 5y + 9
5y = 2x - 9
y = (2/5)x - (9/5)

yeah m is the slope
OpenStudy (anonymous):
ok then what do i do?
OpenStudy (danjs):
any line parallel to that given one , will have the same slope
OpenStudy (anonymous):
so i graph it then?
OpenStudy (danjs):
so you have
y = mx + b
y = (2/5)x + (9/5)

any parallel line to that one will have a slope of 2/5
OpenStudy (anonymous):
oh, so thats the answer?
OpenStudy (danjs):
yea
OpenStudy (anonymous):
k, can you help me with 1 more?
OpenStudy (danjs):
sure

ok
OpenStudy (anonymous):
Which of the following has a slope of 2 and a y-intercept of –4?
(Points : 4)
y = -2x + 4
y = 2x + 4
y = 2x - 4
y = -2x - 4
OpenStudy (anonymous):
oops
OpenStudy (anonymous):
Which of the following has a slope of 2 and a y-intercept of -4?
OpenStudy (danjs):
recall: the form
y = mx + b
m = slope
b = y-intercept
