Answer: 26
Step-by-step explanation:
The equation of the given line above is y=3x-1. The slope of the line is 3/1 (3x) and the y-intercept which is where the line crosses the y-axis is (0,-1) When you plug these parameters into the equation you will get the equation y=3x-1
Tessa made a mistake on line 3.
As you can see, the line below says 8x+12=-20. This is perfectly fine. Though when she gets rid of 12, she adds twelve. So if she did, it would look like 8x+24=-8. No, she made it 8x=-8. When getting rid of something, you must do it's value's opposite. Therefore, it would be 8x=-32. Since subtracting negative by negative is negative.
