Answer:
y = -
x - 
Step-by-step explanation:
Slope intercept form: y = mx + b
To put the equation in slope intercept form, isolate the y:
2x + 3y = -7
3y = -2x - 7
y = -x -
y = x + 1

Answer:
A) 4
Step-by-step explanation:
Area of a triangle formula:
A = 0.5bh
Given:
b = 4
h = 2
Work:
A = 0.5bh
A = 0.5(4)(2)
A = 2(2)
A = 4
We are given with
initial consumption = 13.1
consumption after 17 years = 19.9
P < 0.01
