Midterm Review Part two

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is represented as Ax + By = C, where A, B, and C are constants.

Front

What is the x-intercept of a line?

Back

The x-intercept of a line is the point where the line crosses the x-axis, represented as (x, 0).

Front

Evaluate the expression -x - 6x + 10 when x = 5.

Back

The result is -25.

Front

Evaluate the expression -3x^2 - 5x + 7 when x = -2.

Back

The result is 5.

Front

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

Back

The slope-intercept form of a linear equation is represented as y = mx + b, where m is the slope and b is the y-intercept.

Front

What does 'm' represent in the slope-intercept form?

Back

'm' represents the slope of the line, indicating the steepness and direction.

Front

What does 'b' represent in the slope-intercept form?

Back

'b' represents the y-intercept of the line, the point where the line crosses the y-axis.

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

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

Back

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

Front

What is the significance of the coefficients A and B in the standard form Ax + By = C?

Back

A and B determine the orientation and steepness of the line.
