Answer:
(-2,-1); (-2,-4); (0,-1); (0,-3); (-1,-4); (-1,-3)
Step-by-step explanation:
Just reflect it starting at x=-2
Answer:
the table should show the data
Answer:
y=-3x-1
Step-by-step explanation:
<u>Slope-intercept format:</u>
y = mx+b
m = slope
- In this case, the slope is -3
b = y-intercept
- In this case, the y-intercept is -1
Now we plug it in to get the equation:
y=-3x-1
I hope this helped!

Answer:
<em>(a) x=2, y=-1</em>
<em>(b) x=2, y=2</em>
<em>(c)</em>
<em>(d) x=-2, y=-7</em>
Step-by-step explanation:
<u>Cramer's Rule</u>
It's a predetermined sequence of steps to solve a system of equations. It's a preferred technique to be implemented in automatic digital solutions because it's easy to structure and generalize.
It uses the concept of determinants, as explained below. Suppose we have a 2x2 system of equations like:
We call the determinant of the system
We also define:
And
The solution for x and y is
(a) The system to solve is
Calculating:
The solution is x=2, y=-1
(b) The system to solve is
Calculating:
The solution is x=2, y=2
(c) The system to solve is
Calculating:
The solution is
(d) The system to solve is
Calculating:
The solution is x=-2, y=-7
Answer:
A and D
Step-by-step explanation:
Moving the line left would be moving it onto the y - axis
Therefore the solution would be any point that starts with 0
So (0, 1), (0, 2), (0, -9), etc.
