Option 1! If you expand the bracket and simplify.
The unit rate of the bicycle is 0.3 kilometers per minute.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the y intercept (initial value of y).
Let y represent the km travelled by the bicycle after x minutes. From the graph using the point (0, 0) and (40, 12), hence:
Unit rate (m) = (12 - 0)/(40 - 0) = 0.3 km/min
The unit rate of the bicycle is 0.3 kilometers per minute.
