9e + 4 = -5e + 14 + 13e
9e + 4 = 8e + 14
9e = 8e + 10
e = 10
Hope this helps.
Given two points; A(x₁,y₁) and B(x₂,y₂), the slope "m" is:
m=(y₂-y₁)/(x₂-x₁) or m=(y₁-y₂)/(x₁-x₂)
Therefore:
(-9,5)
(-7,10)
m=(10-5) / (-7-(-9))=5/(-7+9)=5/2
Answer: D. 5/2
Hey the answer is -0.2. You have to divide 10 by both sides to isolate the variable
The answer is called a linear equation :))
