The equation is z = 50t + 200
What is a Linear equation?
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.
Let z be the distance june has traveled.
It is given that the cities 200 miles apart.
So, b = 200.
and speed = 50 mph
m = 50:
Hence, z = 50t + 200
