Math Problem Statement

Write the equation of the line in point-slope form given the point (-3, -2) and the slope of 1.

Solution

To write the equation of the line in point-slope form, we use the following formula:

yy1=m(xx1)y - y_1 = m(x - x_1)

Where:

  • (x1,y1)(x_1, y_1) is the given point,
  • mm is the slope.

Given:

  • Point (3,2)(-3, -2),
  • Slope m=1m = 1.

Now, substitute these values into the formula:

y(2)=1(x(3))y - (-2) = 1(x - (-3))

Simplify:

y+2=1(x+3)y + 2 = 1(x + 3)

So, the equation of the line in point-slope form is:

y+2=x+3y + 2 = x + 3

  1. How do you convert point-slope form to slope-intercept form?
  2. How would you write the equation of a line with a different slope?
  3. What happens if you change the point (3,2)(-3, -2) to a different point?
  4. How do you find the slope of a line given two points?
  5. Can you use point-slope form for vertical or horizontal lines?

Tip: In point-slope form, you can easily identify the slope and a specific point on the line, which helps when graphing.
