To find the equation of a line that passes through a specific point with a given slope, we can use the point-slope form of the equation of a line, which is:
y - y_1 = m(x - x_1)
In this formula:
- (x1, y1) is the given point on the line, which is (4, 3) in this case.
- m is the slope of the line, which is 2.
Now, we can substitute the values into the point-slope form:
y - 3 = 2(x - 4)
Next, we simplify the equation:
- Distributing the slope (2) to (x – 4):
- Now, we’ll add 3 to both sides to isolate y:
- This simplifies to:
y - 3 = 2x - 8
y = 2x - 8 + 3
y = 2x - 5
Thus, the equation of the line that passes through the point (4, 3) with a slope of 2 is:
y = 2x - 5
This linear equation can be used to describe the relationship between x and y for any point on that line.
