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
⇒
.
Answer:
The value of r is 4
Step-by-step explanation:

In order to find the value of r, you need to get rid of denorminator. By multiplying 4 to both sides:
(r/4)×4 = (60/120)×4
r = (1/2)×4
= 2
