Answer:
When we are dividing exponents, there is this rule:

So, in our case we have this:


Answer:
y = -9/10x + 3/10 or y = 3/10(1 - 3x)
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of one another
so slope of line w is -9/10
Using (-3,3) >> y = -9/10x + b
3 = -9/10(-3) + b
3 = 27/10 + b
b = 3 - 27/10 = 30/10 - 27/10 = 3/10
y = -9/10x + 3/10 or y = 3/10(1 - 3x)
