Can someone help me with slope formulas for Algebra 2

determine the slope of the line that contains each of points

1) (-3 , 5) ( -7 , 2)

2) (-9 , -1) (-6 , 2)

3) (4 , 8) (-2 , 12)

4) (2 , -8) (2 , -3)

dertermine the equation of the line that contains each set of points(so that means do the y=mx+b formula...)

1) (13,8) amd (11,12)

2) (-4,7) and (0,10)

3) (-9,6) and (1,5)

4) (-15,7) and (5,20)

given the following find the slope and y-intercept

1) 2x - 7y = 1

2) 3x + 4y= -12

pleasee help! :)

i dont want to answer this for you because then you wouldnt be doing the work and it wouldnt help you, but i'll give you this really big HINT:

to find the slope, take the second y value and subtract the first y value from it. that is your rise.
next, take the second x value and subtract the first x value from it. that is your run.
now put it in fraction form-- put the rise as your numerator (top number) and the run as your denominator (bottom number). If you want you can divide the top by the bottom to make it a decimal if you want, but its still it same value.

im not sure if im right, but it seems right.
