Yes a fraction does indicate a ratio. So do 1/2 Implies a ratio of 1 to 2 which can also be written 1 : 2.
Answer:
Step-by-step explanation:
an equation perpendicular to the equation given will have a slope of -1, because a perpendicular slope is opposite and reciprical. if it goes through the point 4,-1 and has a slope of -1, the y intercept has to be 3. y = -x + 3
parallel lines have to have the same slope of 3.
1/2 times 10 is 10/2 but it reduces to 5. Last ones are 2/15 and 1/6
