I just need the explaination of the formula to tell whether or not it is parallel or intersecting and col linear

thats all it is given, theres a formula for solving but I don't know it.

Hint: the equation y = mx+b has the slope m

ex: y = 9x + 20 has the slope of 9

sorry the lines are not intersecting. Extremely sorry, I made a mistake. They have same slopes, so they should be parallel.

I guess its four right? thats fine

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
4 is the slope, yes
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
since the slope is 4 for both of the lines, the lines are either parallel or collinear

the two lines are collinear if and only if the two yintercepts are the same

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
otherwise, the two lines are parallel

one passes from y=3 and other from y=1, so they are parallel(since slopes are same) but not colinear.
 2 years ago

math_crasher Group TitleBest ResponseYou've already chosen the best response.0
so if its the same its parallel and what happens if its collinear?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
no, if the yintercepts are the same, the lines are collinear if the yintercepts are different, the lines are parallel both cases are true when the slopes are both equal

oh ok i see, so it is collinear right?

what are the yintercepts for both lines?

i need help finding the y intercepts pls
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
y = mx+b b is the yintercept  ex: for y = 2x+11 11 is the yintercept  ex: y = 14x13 which is the same as y = 14x + (13) 13 is the yintercept
 2 years ago

math_crasher Group TitleBest ResponseYou've already chosen the best response.0
ah i see
 2 years ago

math_crasher Group TitleBest ResponseYou've already chosen the best response.0
in this case the y intercepts are the same, which is 4x? And what do I do with the 1 and 3?

to find Y=intercept, put x=0 in each equation. simple. Any point on yaxis is represented as x=0 and y=Y

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
no, that's not the yintercept

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
y = 4x + 1, y intercept is 1

look back up at my 2nd to last post

oh right then the y intercepts aren't the same
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
so the lines are parallel
 2 years ago

math_crasher Group TitleBest ResponseYou've already chosen the best response.0
ah ok what will happen if its intersecting?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
if the slopes are different, then the lines will intersect
 2 years ago

math_crasher Group TitleBest ResponseYou've already chosen the best response.0
what about collinear?
 2 years ago

jim_thompson5910 Group TitleBest ResponseYou've already chosen the best response.1
if the slopes are the same and the yintercepts are the same, then the two lines are collinear
