Front

How do you find the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

Front

What is the slope of the line y = 2x + 3?

Back

The slope is 2.

Front

How do you convert the equation y = mx + b to standard form?

Back

Rearrange it to Ax + By = C, where A, B, and C are integers.

Front

Write the equation of a line parallel to y = -x + 1 that passes through the point (0, 2).

Back

y = -x + 2.

Front

What is the general form of a linear equation?

Back

Ax + By + C = 0, where A, B, and C are constants.
