Here is a great website that is safe and free to help with your math problems. I wouldn't have gotten through 10th grade with out it! It's called mathway. com
Answer:
y - 2 = -3(x - 1).
y = -3x + 5.
3x + y = 5.
Step-by-step explanation:
The slope of the line is (-1-2) / (2 - 1)
= -3.
Using the point slope form of the equation of a straight line:
y - 2 = -3(x - 1) This is one way to write it.
Simplifying the above:
y = -3x + 3 + 2
y = -3x + 5. This is another way called the slope-intercept form.
Now we convert this to the standard form:
y = -3x + 5
y + 3x = 5
3x + y = 5.
Answer:
0
Step-by-step explanation:
Here, we want to find the number of solutions that the equation have.
We can easily find this by solving the equation;
2 + 34x -5 = 3x -3-94x
2-5 + 34x = 3x -94x -3
-3 + 34x = -91x -3
Now since we have -3 on both sides, we can easily cancel out and we are left with;
34x = -91x
This shows that we cannot find x and thus the equation has no solution
