Answer: 
Step-by-step explanation:
1. By definition, two slopes are perpendicular if their slopes are negative reciprocals of each other. So, let's find the slope of the other line.
2. The equation given in the problem is written in Point-slope form:

Where m is the slope.
3. Therefore, the slope of its perpendicular line must be:

4. You have the point (-5,7), so you can substitute it into the point-slope formula to find the equation of the new line:

5. In slope intercept form is:

Answer:

Step-by-step explanation:
Answer: blank 1: 26 blanks 2: 2
Step-by-step explanation:
If you divide 39 by 6 you get 6.5 which is how many cups is in each pizza. Now you multiply 6.5 times 4 and you get 26. Now you take 13 and divide it by 6.5 and get 2.
They shouldn’t have to wait for each other because they are doing everything the same.
Both 3 miles away, both start at the same time, both at current rate
