Answer:
Ax + Ay + 2A = 0 for any nonzero A, for example (A=1): x + y + 2 = 0
Step-by-step explanation:
The equation of a line is
Ax + By + C = 0
so we know that:
A*-3 + B*1 + C = 0
A*5 + B*-7 + C = 0
Let's subtract one from the other:
A*(-3 - 5) + B*(1 + -7) = 0
A*-8 + B*8 = 0
B*8 = A*8
B = A
Let's input B = A into the first two equations
A*-3 + A*1 + C = A*-2 + C = 0
A*5 + A*-7 + C = A*-2 + C = 0
checks out
C = 2A
So for any nonzero A the equation of
Ax + Ay + 2A = 0 produces a line passing between the points. Example would be
x + y + 2 = 0
Answer:
30 por ciento:2250
16 por ciento:1200
Step-by-step explanation:
- Average Rate of Change/Slope Formula:

So using points (6,71) and (2,y), and the slope of 15, plug them into the slope formula as such:

From here we can solve for y. Firstly, solve the subtraction:

Next, multiply both sides by 4:

Next, subtact both sides by 71:

Lastly, multiply both sides by -1, and <u>your final answer will be
, or A.</u>
An appropriate choice among these is
The graph of f is the graph of the equation y = f(x).
_____
Horizontal and vertical axes of the Cartesian plane are conventionally labeled and referred to as "x" and "y", respectively. When we talk about the graph of f(x) in that context, we usually mean the graph of y=f(x). However, this convention may not be followed in all cases. There may be no "y" label on the graph at all, or the horizontal axis may be labeled something other than "x".
