Step-by-step explanation:this is an example and then the question you can answer
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
another example
In order to be parallel to your line, a line has to have the same slope as your line. So it has to have slope −4. Thus any line parallel to the line y=−4x+5 has an equation of the form y=−4x+b, where b is any number.
Answer:

Step-by-step explanation:
This is how you find it
1) Substitute the p into the equation to get 7(-7)-7=-56. Then you get -49-7=-56. This is true
Hope this helps! :)
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12
None, because you need to make over 15,000 a year to be taxed. And with all that money for one year would not be taxed.
