Front

What are the coordinates of the origin in the coordinate plane?

Back

(0,0)

Front

What is the coordinate of point H?

Back

(1,2)

Front

Back

(0,1)

Front

If f(x) = 2x + 1, what is the first step to find f(1)?

Back

Plug a 1 in for all the x's

Front

If g(x) = 3x + 1, what is g(10)?

31

Front

What does the x-coordinate represent in a coordinate pair?

Back

The horizontal position on the coordinate plane.

Front

What does the y-coordinate represent in a coordinate pair?

Back

The vertical position on the coordinate plane.

Front

What is the general form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²).
