In Exercises 1 to 8, find the equation of the line which satisfy the given conditions: Passing through the point (−4,3)(-4, 3) with slope 12\frac{1}{2}.

Correct Answer

The equation of the line is y−3=12(x+4)y - 3 = \frac{1}{2}(x + 4) or x−2y+10=0x - 2y + 10 = 0.

Explanation

This question requires applying the point-slope form of a line. From the textbook, the point-slope form states that for a line with slope m passing through point (x0,y0)(x_0, y_0), the equation is y−y0=m(x−x0)y - y_0 = m(x - x_0). Here, the given point is (−4,3)(-4, 3) and slope m=12m = \frac{1}{2}. Substituting these values gives y−3=12(x−(−4))y - 3 = \frac{1}{2}(x - (-4)), which simplifies to y−3=12(x+4)y - 3 = \frac{1}{2}(x + 4).

Solution Steps

  1. Step 1: Identify the given point (x0,y0)=(−4,3)(x_0, y_0) = (-4, 3) and slope m=12m = \frac{1}{2}.

  2. Step 2: Apply the point-slope form formula: y−y0=m(x−x0)y - y_0 = m(x - x_0)

  3. Step 3: Substitute the values: y−3=12(x−(−4))y - 3 = \frac{1}{2}(x - (-4))

  4. Step 4: Simplify: y−3=12(x+4)y - 3 = \frac{1}{2}(x + 4) or x−2y+10=0x - 2y + 10 = 0
