Use the two points whose coordinates are shown to find the point-slope form of the equation of the line that models the percentage of adults on diets, y, x years after 1987.

Because there's no picture provided, I can just give two points in order to formulate the equation using the point-slope formula. The x is in years while the y is in percentage. Suppose point 1 is (2, 35) and point 2 is (7,80).

Point Slope Formula: y - y₁ = [(y₂ - y₁)/(x₂ - x₁)](x - x₁)
Substituting,

y - 35 = [(80 - 35)/(7 - 2)](x - 2)
y - 35 = 9(x - 2)
