The equation y = mx + b is known as the slope-intercept form of a line. Which equation shows y = mx + b correctly solved for x?
y = mx + b
mx + b = y
mx = y - b
x = (y-b)/m or (1/m)y - b/m
To solve the equation y = mx + b for x, follow these steps:
1. Begin with the equation: y = mx + b
2. Subtract b from both sides of the equation to isolate the term mx: y - b = mx
3. Divide both sides of the equation by m to solve for x: (y - b) / m = x
Therefore, the equation that shows y = mx + b correctly solved for x is:
x = (y - b) / m
