Answer:
The tree was 40 in tall when planted
The tree's growth rate is 10in per year
Ten years after Planting, it is 140 inches tall
Step-by-step explanation:
original(slope intercept form) : y = 10x + 40
y = 10(10) + 40
y = 100 + 40
y = 40
First, we determine the slope of the line given, y = 2x + 5
The equation is in slope-intercept where in the slope of the line is the numerical coefficient of x. The slope is therefore 2.
The equation of the new line becomes,
y - 6 = 2(x - 4)
Simplifying, y = 2x - 2
