Front

What is the equation that models Edwin's walk downhill towards the base of the trail if he walks at a rate of 3.5 mi/h from the top of a 6-mi trail?

Back

Front

Solve the equation: 2x - 3 + 4x = 27

Back

x = 5

Front

If a system of linear equations has one solution, what does this mean about the two lines?

Back

The lines are intersecting.

Front

How many hours pass before Thato and Edwin meet on the trail if Thato walks uphill at 2.5 mi/h and Edwin walks downhill at 3.5 mi/h?

Front

What is the slope-intercept form of a linear equation?

Back

Front

Define a system of linear equations.

Back

A system of linear equations is a set of two or more linear equations with the same variables.

Front

What does it mean if two lines are parallel in a system of equations?

Back

If two lines are parallel, it means they have the same slope and will never intersect, indicating no solution.

Front

Back

The y-intercept is 3.

Front

How do you find the solution to a system of equations graphically?

Back

You find the solution at the point where the two lines intersect.
