Dividing by 10 is simple; just move the decimal place one digit to the left. So, 8.0 would then be 0.8. However, it is imperative you show your working out:
8/10=0.8
To find the slope and y-intercept, you need to get the equation into slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.
-12x - 4y = 10
+12x +12x
-4y = 12x + 10
/-4 /-4
y = -3x - 10/4
