Convert the linear equations below given in standard form into Slope Intercept Form and write the slope and y-intercept for each. (the first one is done for you)
3x + 2y = 10
2x – 4y = 12
3x + 5y = 20
-x – 6y = 18
5x + 8y = 25
-3x + 12y = 24

Line passes through (3,1) with a slope of 2.
Line passes through (5,8) with a slope of 2.
Line passes through (-4,2) with a slope of 3.
Line passes through (5,-2) with a slope of -0.5.
