Answer:
-7/45
Step-by-step explanation:
First, find the lowest common denominator for 9 and 15. It's 45. Make both fractions over 45 by multiplying the top and bottom by the same number.
Since 15*3=45, multiply the top by 3 also. Since 9*5=45, multiply the top by 5 also.
Combine the fractions
Answer in lowest terms
slope (m) = (y₂ - y₁)/(x₂ - x₁)
-2/1 = (a - 1)/(5 -(-5))
-2 = (a - 1)/10
-20 = a - 1
-19 = a
Answer: a = -19
