To write an equation in point-slope form, you need a specific point on the line and the slope of the line. The point-slope form of a linear equation is given by the formula:
y – y1 = m(x – x1)
Where:
- (x1, y1) is a point on the line.
- m is the slope of the line.
Let’s say you have a point (2, 3) and a slope of 4. Plugging these values into the formula gives:
y – 3 = 4(x – 2)
This equation represents the line that passes through the point (2, 3) with a slope of 4. To create your own equation, simply substitute your specific point and slope into the formula. Remember, the point-slope form is particularly useful when you know a point and the slope, enabling you to quickly express the line’s equation!
