Step-by-step explanation:
given that 
Normalizing the function we get





Put in slope intercept form so the first equation would be y=-x-9 then the second one will be y=-5/2x-16
Answer:
y + 1 = -2/7 (x + 4)
Step-by-step explanation:
Find the slope using y₂ -y₁ /x₂ -x₁
m = -3 + 1 / 3 + 4
m = -2/7
Plug the m, x and y into the point slope equation y - y₁ = m ( x - x₁)
y + 1 = -2/7 (x + 4)
The answer would be 1/12.
1/16 * 4/3
1* 4 over 16 * 3
4 over 16 * 3
4/48
1/12.
