Question

Find the equation of the line that represents the enrollment y in terms of x years since 1990.

a) y = mx + b
b) y = b - mx
c) y = b + mx
d) y = mx

Answer 1

The equation that represents the enrollment, y, in terms of x years since 1990 is y = mx + b. In this equation, 'm' represents the slope and 'b' represents the y-intercept.

Step-by-step explanation:

The equation that represents the enrollment, y, in terms of x years since 1990 is:

y = mx + b

In this equation, 'm' represents the slope of the line, which is the rate of change in enrollment over time. 'b' represents the y-intercept, which is the initial enrollment at x = 0 (in this case, the enrollment in 1990).
