Answer:
y = 2x
Step-by-step explanation:
Step-by-step explanation:
Let
y ----> the height in inches
x ----> the time in hours
we have the ordered pairs
(1, 2), (2, 4), and (3, 6).
step 1
Find the slope
take two points to calculate the slope
(2, 4), and (3, 6)
The formula to calculate the slope between two points is equal to
m = 2 in/h
step 2
Find the equation of the line in point-slope form
we have
m =2
point (2,4)
Convert to slope-intercept form
isolate the variable y
y = 2x
