7x=5y Find the slope and the y intercepts of each line whose equation is given?
You want to put it in Slope-Intercept Form, which is y=mx+b. m=Slope b=y-intercept
ok y intercept is 0?
Correct!
so how do i get from 7x=5y to Y=(7/5)x+0
You're just isolating the y by itself... so you divide each side by 5. That leaves you 7/5x=y
how do i lose the x?
You don't. The x is part of the ordered pair (x,y) for the equation.
Are you still looking for the slope?
no i just know that 7/5 is the slope and 0 is the intercept.. didnt know if the x is 7/5 and y is o?
No. It's 7/5 times x equals y. In the full Slope-Intercept Form, it's 7/5x+0=y Where 7/5 is the slope, and 0 is the y-intercept.
ok so sorry i dont get this stuff. if 7/5 is times x, where did x go? is x =1?
x is whatever. the x and y in the equation is any ordered pair. If you're only looking for the y-intercept and the slope, the x doesn't matter. As long as you realize that the slope is coefficient of x.
oh ok. got it.. thanks.. can u help with this one too? this is my last week in principles in algebra and i have to pass to go on to next class. I promise, I will not get a job requiring this stuff!! lol here is problem....Write an equation of the line containing the specified point and perpendicular to the indicated line (4, −2), x = 1
Okay. Sorry, this is taking me a minute. lol
oh ok.. lol i understand and this isnt even my final! lol just two questions..
For lines to be perpendicular, the slope of line one times the slope of line two must equal -1.
ok? lol well i have to go attend to the kiddos..lol i will have to come back tomorrow for more help.. if you are here i will holla at ya! thanks so much for your help so far!
No problem. Glad I could help a little!
