Math Problem Statement

Write an equation of the line in point-slope form that passes through the given points (2,3) and (3,7).

Solution

To write the equation of a line in point-slope form, we first need to calculate the slope (mm) using the two points provided: (2,3)(2, 3) and (3,7)(3, 7).

Step 1: Calculate the slope (mm)

The slope formula between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) is: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the given points: m=7332=41=4m = \frac{7 - 3}{3 - 2} = \frac{4}{1} = 4

Step 2: Use the point-slope formula

The point-slope form of a line is: yy1=m(xx1)y - y_1 = m(x - x_1)

We can use either of the given points. Let's use (2,3)(2, 3): y3=4(x2)y - 3 = 4(x - 2)

This is the equation of the line in point-slope form.

Would you like further details on solving this, or any additional clarifications?

Here are some related questions to expand your understanding:

  1. How do you convert the point-slope form to slope-intercept form?
  2. What would the equation look like if you used the point (3,7)(3, 7) instead?
  3. Can you use the point-slope form to find the equation of a line perpendicular to this one?
  4. How would you determine if a third point lies on this line?
  5. What is the significance of the slope value in this line's equation?

Tip: When working with two points, always ensure you compute the slope first, as this defines the steepness and direction of the line.
