Question
- Find the equation of the line given the points (2, 3) and (5, 12) lie on this line.2. Explain how you checked that your answer was correct
Solution
-
To find the equation of the line, we first need to find the slope (m). The formula for the slope when given two points (x1, y1) and (x2, y2) is m = (y2 - y1) / (x2 - x1).
Substituting the given points (2, 3) and (5, 12) into the formula, we get:
m = (12 - 3) / (5 - 2) = 9 / 3 = 3
Now that we have the slope, we can use the point-slope form of the line equation, which is y - y1 = m(x - x1).
Substituting m = 3 and the point (2, 3) into the equation, we get:
y - 3 = 3(x - 2)
Simplifying this equation gives us the equation of the line:
y = 3x - 3

To check if the equation is correct, we can substitute the given points into the equation and see if they satisfy it.
For the point (2, 3), substituting x = 2 into the equation gives us y = 3*2 - 3 = 3, which is correct.
For the point (5, 12), substituting x = 5 into the equation gives us y = 3*5 - 3 = 12, which is also correct.
Therefore, the equation y = 3x - 3 is indeed the equation of the line that passes through the points (2, 3) and (5, 12).
