How do you write an equation from a constant speed?

Back

If a person travels at a constant speed, the distance (d) can be expressed as a function of time (s) using the equation d = speed * time.

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is 0.

Front

What is the general form of a linear equation?

Back

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
