Answer:
Step-by-step explanation:
The question lacks appropriate diagram. Find the diagram attached.
Slope is the change in coordinate of the y coordinate to the x coordinate.
Mathematically, slope m = ∆y/∆x
From the diagram ∆y is the same as 3 (along the vertical) while ∆x is the same as 1 (along the horizontal)
m = ∆y/∆x = 3/1
∆y/∆x = 3/1
y/x = 3/1
Cross multiply
y × 1 = 3 × x
y = 3x
Hence the slope of the line is y = 3x
Answer:
The rate of cases is per hour
Step-by-step explanation:
we are given
Total number of cases =5
total time is
hour
we can simplify it
total time is
hour
hour
we can use formula
rate of cases = ( total number of cases)/( total time)
now, we can plug values
Rate of cases is
