- Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
So remember that <u>parallel lines have the same slope.</u> And since Line a's slope is 5/7, and line a and b are parallel to each other, this means that <u>line b's slope is 5/7.</u>
When finding the probability of two things happening, you multiply the probability of each individual thing happening. The chances of heads are 1/2 and the chances of not a 3 are 5/6. 1/2*5/6 = 5/12. The probability of that is 5/12
The answer is 2a-4b. Hope this helps!
