Writing Linear Equation Test

Front

What is the y-intercept in the equation y = 5x - 4?

Back

-4

Front

What is the standard form of a line?

Back

Ax + By = C

Front

Write an equation that is parallel to the line y = x - 5 through the point (1, -2).

Back

y = x - 3

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

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

Front

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

Back

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

Front

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

Back

y - y1 = m(x - x1), where (x1, y1) is a point on the line.

Front

How do you convert from slope-intercept form to standard form?

Back

Rearrange y = mx + b to Ax + By = C.

Front

What is the significance of parallel lines in terms of slope?

Back

Parallel lines have the same slope.

Front

What is the significance of perpendicular lines in terms of slope?

Back

Perpendicular lines have slopes that are negative reciprocals of each other.
