What is the slope of the line which passes through (4, 5) and (0, 1)?

OpenStudy (anonymous):

(1-5)/(0-4) =-4/-4 =1

OpenStudy (anonymous):

can you help me with more? plz?

OpenStudy (anonymous):

i really need help

OpenStudy (anonymous):

What is the equation in point-slope form of the line passing through (1, 2) and (2, 5)?

OpenStudy (anonymous):

y-2=3(y-1)

OpenStudy (anonymous):

Factor 3x2 - 6x - 9 completely.

OpenStudy (anonymous):

y-2=3(x-1) i meant

OpenStudy (anonymous):

okay thank you..can you do that other one? i will give you a medal

OpenStudy (anonymous):

which one?

OpenStudy (anonymous):

Factor 3x2 - 6x - 9 completely. and Simplify (x - 4)(x2 + 3x + 2).

OpenStudy (anonymous):

3(x^2-2x-3)=3(x+1)(x-3) (x-4)(x^2+3x+2)=(x-4)(x+1)(x+2)

OpenStudy (anonymous):

the second one is wrong

OpenStudy (anonymous):

Simplify (x - 4)(x2 + 3x + 2). x3 - x2 + 14x - 8 x3 + 7x2 - 10x - 8 x3 - x2 - 10x - 8 x3 + 7x2 + 14x - 8

OpenStudy (anonymous):

expand it x^3 -x^2-10x-8

OpenStudy (anonymous):

so C?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

thanks!
