Answer:
D
Step-by-step explanation:
First, find the slope using the slope formula. The slope is 3.
Now plug in any of the x and y values and the value of the slope into the slope-intercept form equation to solve for b.
9=3(3)+b, solve for b
b=0, Now convert the equation y=3x into slope-intercept form.
y-9=3(x-3) This is the equation of the line, the plant will be about 36 cm tall after 12 months.
