X = 12, because there is only one answer that has a number bigger than 9 :)
Answer:

Step-by-step explanation:
The point is located in Quadrant II of the graph, where x-values are negative and y-values are positive.
Each marking on the graph represents one unit of distance. The two <em>axes</em> meet at the origin, where the coordinate point is equal to
.
So, you can count backwards once from the origin to get your x-value ⇒
and count up upwards four times from
to get your y-value ⇒
.
Finally, place these in a coordinate point
⇒
.
3/20 = 0.15
0.15 * 100 = 15
You would need to use 15 eggs for 100 pancakes.
X = 352.3 [your work is correct]
then the perimeter would be 352.3 + 352.3 + 280 + 280 = 1,264.55
Perpendicular, slope is reciprocal and opposite
so answer is C. -7
