find the slope and y-intercept of the line
1 9x+y=8
2 12x+3y=9
3 6x-2y=2
4 2x+5y=10
1) 9x + y = 8
y = -9x + 8
slope = -9, y-intercept = 8
2) 12x + 3y = 9
3y = -12x + 9
y = -4x + 3
slope = -4, y-intercept = 3
3) 6x - 2y = 2
-2y = -6x + 2
y = 3x - 1
slope = 3, y-intercept = -1
4) 2x + 5y = 10
5y = -2x + 10
y = (-2/5)x + 2
slope = -2/5, y-intercept = 2
