Answer:
Yes
Step-by-step explanation:
This relation is a function. Functions must have unique x-values for every y-value, this relation meets those requirements. Also, since this is a graph you can use the vertical line test. To pass the vertical line test you must be able to draw a vertical line on the graph and have it intersect with the function in no more than one place.
How generous
x+3=8
minus 3 both sides
x+3-3=8-3
x+0=5
x=5
You need to figure what increment each dash line represents. Since given -6 and -14 is 2 dash lines away, you find the difference
-14-(-6) = 8
Since it was 2 dashes away, 8/2 = 4
So, each increment is by 4.
Since this is the negative direction and the blue dot is 4 increments away,
-14-4-4-4-4= -30
Y = 15x + 50
85 = 15x + 50
35 = 15x
X = 2.3333
X= 2 hours
Option 1 because they both need to start sequence from 2
