Suppose that a certain strain of pea plant requires 14 days to reach a height
of 6 inches and 30 days to reach a height of 16 inches.
Write a linear equation in slope-intercept form that models the height of the plant after x days
:
Assign the given data as follows
x1=14; y1=6
x2=30; y2=16
:
Find the slope: m = = = is the slope
:
Use the point/slope formula: y - y1 = m(x-x1)
y - 6 = (x - 14)
y - 6 = x - 8.75
y = x - 8.75 + 6
y = x - 2.75, is the equation
