Its .2857142857(long decimal xD)
- 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>
Answer:
see explanation
Step-by-step explanation:
(a)
2x + 10 ← factor out 2 from each term
= 2(x + 5)
(b)
5x - 15 ← factor out 5 from each term
= 5(x - 3)
(c)
8x + 6 ← factor out 2 from each term
= 2(4x + 3)
(d)
12x - 8 ← factor out 4 from each term
= 4(3x - 2)
