Answer:
5ab + 8 - 1a^2.
Step-by-step explanation:
Combining like terms, we get 3a^2 - 4a^2 = -1a^2. We get 9ab - 4ab = 5ab. Then we get, 5 + 3 = 8. Together this is 5ab + 8 - 1a^2

I hope that’s correct ☺️
Slope of tangent line = dy/dx = 2x+3
k is y_intercept of tangent line
2x+3 = -1
x = -2
y = (-2)^2+3(-2)+1 = -1
tangent line passes through point (-2,-1)
k = x+y
k = -2 -1
k = -3
Every time the y-value decreases by 1, the x-value increases by 2, so the slope is -1/2 throughout the line.
