Answer:
-1 is on the Y axis (vertical) Slope is 1/6
Step-by-step explanation:
-1 is on the Y axis. Go up 1 a right over 6. <- that is the slope
100/20=5
11×5=55
11/20 = 0.55
Answer:


Step-by-step explanation:
Connecting points O and E and points O and J, we get triangle EOJ. This triangle is equilateral triangle, because OJ=OE=JE=r=10 cm.
Since EP⊥IJ, then segment JP is the height of the triangle EOJ.
The height of the equilateral triangle can be found using formula

where a is the side length.
So,

Therefore JP is 5√3 cm
k= 4/9 or 0.444 in decimal form.
hope this helps!
