How do you convert Standard Form to Slope-Intercept Form?

Back

To convert from Standard Form (Ax + By = C) to Slope-Intercept Form (y = mx + b), solve for y in terms of x.

What does the y-intercept (b) represent in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis, indicating the value of y when x = 0.

What does it mean if the slope is zero?

Back

If the slope is zero, the line is horizontal, meaning y does not change as x changes.
