Question

What would most likely be the approximate height of the plant after 7 weeks?

5.2 centimeters
7.6 centimeters
8.7 centimeters
12.7 centimeters

Answer 1

5.2 centimeters

Explanation:

Line is passing through the points (0, 1) & (5, 4)

y-intercept (b) = 1

Slope of line (m) = (4 - 1)/(5 - 0) = 3/5 = 0.6

Equation of line in slope intercept form is given as:

y = mx + b

Plugging the values of m and b in the above equation, we find:

y = 0.6x + 1

Plug x = 7

y = 0.6*7 + 1

y = 4.2 + 1

y = 5.2 centimeters
