How to simplify 16/18

8/9

Step-by-step explanation:

find the highest common factor of the numerator and denominator and then divide both by that factor

Listing factors of numerator and denominator

16: 1,2,4,8,16

18: 1,2,6,9,18

from the above we can see that the HCF is 2, so divide numerator and denominator by 2

16/18 (divide numerator and denominator by 2)

= 8/9  (simplified)

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: y = -2.5x - 15
