What is Standard Form in mathematics?

Back

Standard Form is a way of writing numbers or equations in a specific format. For linear equations, it is typically written as Ax + By = C, where A, B, and C are integers.

How do you find the slope from the equation in Standard Form?

Back

To find the slope from the equation Ax + By = C, rearrange it to slope-intercept form (y = mx + b) and identify the coefficient of x (m) as the slope.

What is the y-intercept of a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the slope-intercept form y = mx + b.

How do you find the y-intercept from the equation 3x + 4y = 24?

Back

Set x = 0 in the equation. 4y = 24, so y = 6. The y-intercept is (0, 6).

What is the x-intercept of a linear equation?

Back

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

How do you find the x-intercept from the equation 4x - 10y = 20?

Back

Set y = 0 in the equation. 4x = 20, so x = 5. The x-intercept is (5, 0).

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x. It indicates how steep the line is.

How do you convert the equation x - 3y = 6 to slope-intercept form?

Back

Rearrange to y = (1/3)x - 2. The slope is 1/3 and the y-intercept is -2.

What is the slope of the line represented by the equation 7x + 2y = -28?

Back

Rearranging gives y = -7/2x - 14. The slope is -7/2.

Front

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

Back

A and B determine the slope of the line. If A = 0, the line is horizontal; if B = 0, the line is vertical.
