Answer:
Step-by-step explanation:
A line is perpendicular to another if its slope is the negative reciprocal of the other.
Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope . The negative reciprocal of that is , which is the slope of the third answer choice.
It represents the thousandths.
I think to turn 193% to decimal is you have to divide it by 100.
193/100= 1.93
When you write it as a fraction 93/100 (there are two decimal number, so it would be over a hundred) and simplify it. You have to remember that you have a whole number and just add it to the fraction.
Hope that this will help you.
