Flashcard review questions

Front

Write the equation in point-slope form of the line that passes through the point (4, -7) with a slope of -1/4.

Back

y + 7 = -1/4(x - 4)

Front

What is the standard form of a linear equation?

Back

Ax + By = C

Front

Write the equation of the line with slope m = 5 that passes through the point (-1, -3).

Back

y = 5x + 2

Front

What is the equation of the line in point-slope form given a slope of ⅔ and the point (-4, 7)?

Back

y - 7 = ⅔(x + 4)

Front

What is the slope formula?

Back

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

Front

What does point-slope form represent?

Back

It represents the equation of a line using a point on the line and its slope.

Front

How do you convert point-slope form to slope-intercept form?

Back

Isolate y to get y = mx + b.

Front

What is the slope of a line that is vertical?

Back

The slope is undefined.

Front

What is the slope of a line that is horizontal?

Back

The slope is 0.

Front

What does the 'm' represent in the equation y = mx + b?

Back

The 'm' represents the slope of the line.
