Answer:
I believe the answer would be y = -(1)x - 2
Step-by-step explanation:
First, you look at where the line appears to cross the x-axis. In this problem, it appears to cross at just about -1. Then, you look at where the line crosses the y-axis. It does that at -2 in this problem.
Then, you just plug those numbers into the y = mx + b form. Alternatively, you could just write -x instead of -1x. I just put the -1 to show you.
Edit: If -1x is wrong, you may want to try -0.5x. It's pretty ambiguous as to where the line actually crosses the x axis.

Answer:
Step-by-step explanation:
xy = 300
x + y = 50 Solve for y
y = 50 - x substitute into xy = 300
x(50 - x) = 300 Remove the brackets.
50x - x^2 = 300 Bring the left to the right.
0 = x^2 - 50x + 300
This is a quadratic. It will have 2 solutions.
a=1
b = - 50
c = 300
Put these into the quadratic equation.
It turns out that x has two values -- both plus
x1 = 42.03
x2 = 6.97
x1 + y1 = 50
42.03 + y = 50
y = 50 - 42.03
y = 7,97
(42.03 , 7.97)
====================
x2 + y2 = 50
6.97 + y2 = 50
y2 = 50 - 6.97
y2 = 43.03
(6.97 , 43.03)
