To write an equation in point-slope form, you can use the formula:
- y – y1 = m(x – x1)
Where:
- (x1, y1) is a point on the line (in this case, (8, 3))
- m is the slope of the line (which is 8 here)
Now, we can substitute the values into the formula:
- Point: (8, 3) → x1 = 8, y1 = 3
- Slope: m = 8
Substituting these values gives us:
y - 3 = 8(x - 8)
This equation, y – 3 = 8(x – 8), is in point-slope form. You can use this equation to find any point on the line or further manipulate it if needed. For example, you can convert it to slope-intercept form (y = mx + b) if required:
y - 3 = 8x - 64 → y = 8x - 61
So, the line through the point (8, 3) with a slope of 8 can be expressed in point-slope form as:
y - 3 = 8(x - 8)
And in slope-intercept form as:
y = 8x - 61
