1-what you do is have x be a number such as 1 so negative 3 times 1 plus 1 is 2-. To graph this you would make the four quadrands and plot the point -2 then you would find another point such as -5 and draw a line connecting the two and you would just make the line go all the way through the quadrants.
2-you find where the line goes for this (you graph it)
wish i could help moreish but u hav 2 go sry
maybe try an algebra website???

the subject count number is mixtures. you decide directly to work out what proportion mixtures of four human beings you will get out of 8. In straightforward arithmetic words, you decide directly to locate 8C4. Typing that in the time of your scientific calculator supplies you the respond. right this is the way you do the working. kind of conceivable 4-guy or woman communities out of 8 pupils = 8C4 8C4 = (8x7x6x5)/(4x3x2x1) = 1680/24 = 70 mixtures.

Are you just asking Yahoo! Answers members to do your homework for you?
I suggest going in for tutorials at your school or forming a study group. If you're not understanding ANY of those problems then you're going to be in trouble in your classes.

you can draw them on a sheet of paper with a grid, there's nothing else we can do
look up the definitions online
Google define: perpendicular for example
