Slope intercept form is y=mx+b
You multiply both sides by 9 first so you have -45=y-7. then add 7 to both sides to get y=-38
Answer:
The x-axis is always the the horizontal axis which represents the independent variable
The y-axis is always the vertical axis which represents the dependent variable
Hope this helps!
Answer:

Step-by-step explanation:
