i have more than one question so if u no any of the answers please tell me

1.) write the point-slope form of the equation of the line with slope -2 passing through the point ( -5, -9).

2.) write the point-slope form of an equation of the line through the points at ( -9, -9) and ( 6, -6).

3 find an equation of the line with the slope 9 and y-intercept 3.

4.) find the slope-intercept form of the equation of the line that passes through the point ( -1, 1) and has slope 8.

5.) give the intercepts of 2x-4y = -1. then graph the equation.

6.) find the slope-intercept form of the line passing through the point (5,2) and parallel to the line y = 2x+6.

7.) find f(-7) if f(x) = 5x-6.

8.) find f(-4) if f(x) = 2x+5.

12.) find the slope of a vertical line.

13.) find the slope of a horizontal line.

14.) write the point slope form of a line that passes through the point (2,4) and has a slope of -4.

15.) write the point slope form of a line that passes through the points (4,6) and (2,5).

16.) write an equation in slope-intercept form of the line having the given slope and passing through the given point.

m=3 (4,2)

17.) m= 1/4 (-8,6)

18.) write an equation in slope-intercept form of the line passing through each pair of points.

(1,3) and (-3,-5)

19.) (4,5) and (-5,5)

20.) find the x and y-intercept, then graph the equation.

-3x+4y=12

21.) 5x+y=5

22.) find the slope and y-intercept, then graph the equation.

y=3x-1

23.) y=3/4x-4

solve and graph the fallowing:

24.) x-7<-3

25.) x+5>or = too 1.

26.) 6x> or = too 48.

27.) -10b < or = too 120.

28.) 5(7-3x)> 12.

29.) 5x+3< or = too 2x+9.

30.) 2> 3x+2 > -13.

31.) x-5 > -3.

    Aww -- come on! Do you really expect someone on Jiskha to do your homework for you?

    We might have helped you with two or three problems that confuse you. However, 31 problems show that you're just trying to cheat!

    7.) find f(-7) if f(x) = 5x-6
    You just plug in the -7
    5(-7)-6=?
    24.) x-7<-3
    +7 +7
    x <?
    28.) 5(7-3x)> 12.
    35-15x>12
    -15x>-23
    x>?

    You must attempt the problems yourself. Nobody is going to solve them for you.
