A. 1/6, 6 possible outcomes with 1 desired result.
B.67/450 will give you the answer of 14.888...% I'm going to assume your teacher will let you round to 15 so the chances are 15/100 and in simplest form is 3/20.
1 is your answer -+- is a positive
6 * 4x = 24x
6 * 5 = 30
3 * x = 3x
3 * 8 = 24
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
subtract 3x from both sides
21x + 30 = 27
subtract 30 from both sides
21x = -3
divide both sides by 21
x = -1/7
so you will have to convert it to slope intercept form which is y=mx+B so you will have to isolate the y
6y+8x=24 subtract 8x to both sides
6y=-8x+24
divide 6 by both sides
y= -8/6x + 4
simplify
y= -4/3x + 4
the slope of the line is -4/3
