Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
To put this into slope-intercept form, you need to isolate/get the variable "y" by itself in the equation:
8x - 6y = 6 Subtract 8x on both sides
8x - 8x - 6y = 6 - 8x
-6y = -8x + 6 Divide -6 on both sides to get "y" by itself
Answer:
1/2 and 13/18 respectively
Step-by-step explanation:
even-number results:
2, 4 6 ,8, 10 and 12
the combinations of each result are respectively
1+3+5+5+3+1 = 18
The total number of combinations on a roll pair is 36
then the probability of obtaining an even result is:
p = 18/36 = 1/2 or 0.5
so that the result is less than nine, we eliminate the combinations of results 9, 10, 11 and 12:
4 + 3 + 2 + 1 = 10
36 -10 = 26
the probability of obtaining a result less than nine is:
p = 26/36 = 13/18 or 0.72
Hope this helps

Answer:
y=-5/4 + -1.25
Step-by-step explanation:
y1 - y2 over x1 -x2
5- -5 =10
-5-3 =-8
simplify: -10/8 which is -5/4 *THAT IS YOUR SLOPE*
Now to find the y intercept pick a point. I chose (-5,5) and plug in for y=mx+b
y will be 5 ; m is your slope so -5/4 ; x is -5 and we don't have out b yet.
5=-5/4(-5) + b
multiply -5/4 and -5 = 6.25
then just subtract -5 and -6.25 = -1.25 which is your y intercept
y= -5/4 + -1.25
