<span>Slope-intercept form is y = mx + b
m is the slope
b is the y-intercept
7x = 14y - 8
7x + 8 = 14y {added 8 to each side}
(1/2)x + (8/14) = y
slope is 1/2
A line perpendicular would have a slope of -2 {the negative reciprocal of 1/2}
#1 y = -2x - 7 {it is the only one with a slope of -2}</span>

Kaylani is going to make a blanket by sewing a 4-foot long piece of ribbon along the diagonal of a piece of rectangular fabric. She wants the length of the blanket to be 18 inches longer than the width. What is the approximate perimeter of the blanket? Round to the nearest inch.
Answer is 9/2 because
0/8+3/2+/32
4/0+0/32
Simplified 9/2
Answer: second option
Step-by-step explanation: To solve this problem, we will need to plug in the value of “x” into our equation to see if it makes sense.
Let’s start by going in order.
-4.9 = -5.7 + 10.6 = 4.9
This will not be the answer because it’s positive 4.9 not negative.
Let’s go on to the last one. If we add positive 0.8 to negative 5.7 we will get the answer of -4.9 and this makes sense.
The answer is 75 % you just have to divide 84 and 112 and u get 75%
