Front

What is the slope of the line represented by the equation y - 3 = 5/3(x - 6)?

Back

5/3

Front

Write the equation of a line in standard form that goes through the points (4, -10) and (-1, 5).

Back

3x + y = 2

Front

What is the slope of the line represented by the table of values if the slope is -3/2?

Back

-3/2

Front

Write the equation of the line in point-slope form with a slope of 2/3 through the point (4, -9).

Back

y + 9 = 2/3(x - 4)

Front

What is the slope of the line given by the equation 4x - 3y = 24?

Back

4/3

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x (rise/run).

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

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

Back

Rearrange the equation y = mx + b to the form Ax + By = C.

Front

What does the point-slope form of a linear equation look like?

Back

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

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.
