Answer:

Step-by-step explanation:
the first - is for reflection
-2 is for translating right (its essentially)
+9 is for translation up
lmk if you want be to explain more
25 000,000/10,000
Cross out equal amounts of 0's from both numbers:
There are 4 0's in 10,000, so remove 4 0's from both numbers to get:
2500/1
Any number over 1 is that number:
2500/1 = 2500
Answer:
Step-by-step explanation:
We first need to find the slope of the given line. Putting that standard form of a line into slope intercept:
12y = -3x - 6 so

In this form we can easily determine that our slope is -1/4. That means that the perpendicular slope, the opposite reciprocal, is +4. We will write first the point slope of the new line using our given point, then solve it for y, putting it into slope-intercept form. y - (-7) = 4(x - (-1)) and
y + 7 = 4x + 4 so
y = 4x + 4 - 7 so
y = 4x - 3
