To find the equation of a line given a point and a slope, we can use the point-slope form of a linear equation. The point-slope form is given by:
y – y1 = m(x – x1)
Where:
- (x1, y1) is a point on the line. In your case, this is (7, 2).
- m is the slope of the line. Here, the slope is 3.
Now we can plug the values into the equation:
y – 2 = 3(x – 7)
Next, we’ll simplify this equation:
y – 2 = 3x – 21
Now, we’ll add 2 to both sides:
y = 3x – 21 + 2
y = 3x – 19
Thus, the equation of the line that passes through the point (7, 2) with a slope of 3 is:
y = 3x – 19
