Answer: 17/18
Step-by-step explanation: You have to find the least common denominator first, since 1/9 and 5/6 have different denominators. The least common denominator is 18. Multiply both the numerator and the denominator of each fraction by the number that makes its denominator equal to the least common denominator.
The equation then becomes 2/18 + 15/18 which equals 17/18 ^-^
FIND THE SLOPE
The line passes through (0,1) and (2,0)
Use formula of the slope to find the slope
m = (y₂ - y₁)/(x₂ - x₁)
m = (0-1)/(2-0)
m = -1/2
The slope is -1/2
FIND THE Y-INTERCEPT
The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
Answer: second option
Step-by-step explanation:
Cost of paperback books = $1x = $x
Cost of hardcover books = $2y
Given Greg can spend a MAXIMUM of $20,
Cost of Paperback books + Cost of hardcover books must be at most 20.
Inequality of this situation =

The correct answer would be C., I believe, because you take the opposite of the coordinate and subtract one. Hope this was helpful! (:
