Give the slope and y-intercept of each line whose equation is given. Assume that B ≠ 0. Ax = By - C

검증된 단계별 안내
1
Start with the given equation: \(Ax = By - C\).
Rearrange the equation to solve for \(y\) in terms of \(x\). Add \(C\) to both sides and then divide both sides by \(B\): \(By = Ax + C \implies y = \frac{A}{B}x + \frac{C}{B}\).
Identify the slope \(m\) from the equation in slope-intercept form \(y = mx + b\). Here, the slope is \(m = \frac{A}{B}\).
Identify the y-intercept \(b\) from the equation. The y-intercept is the constant term \(b = \frac{C}{B}\).
Summarize: The slope of the line is \(\frac{A}{B}\) and the y-intercept is \(\frac{C}{B}\).

Rearranging Linear Equations

To find the slope and y-intercept from an equation like Ax = By - C, you must isolate y on one side. This involves algebraic manipulation such as adding, subtracting, and dividing terms to rewrite the equation in slope-intercept form.

Slope and Y-Intercept Definitions

The slope measures the steepness of a line, calculated as the ratio of vertical change to horizontal change. The y-intercept is the point where the line crosses the y-axis, found by setting x = 0 in the equation.
