Math Problem Statement

The equation of line s is y= – 4x– 5 3 . Line t includes the point ( – 3,3) and is parallel to line s. What is the equation of line t?

Solution

To find the equation of line tt, we follow these steps:

  1. Identify the slope of line ss: The equation of line ss is given as: y=43x5y = -\frac{4}{3}x - 5 The slope (mm) of line ss is 43-\frac{4}{3}.

    Since line tt is parallel to line ss, its slope will also be 43-\frac{4}{3}.

  2. Use the point-slope form of the line equation: The point-slope form is: yy1=m(xx1)y - y_1 = m(x - x_1) where (x1,y1)(x_1, y_1) is a point on the line, and mm is the slope.

    For line tt, the given point is (3,3)(-3, 3) and the slope is 43-\frac{4}{3}.

    Substituting these values into the point-slope form: y3=43(x(3))y - 3 = -\frac{4}{3}(x - (-3)) y3=43(x+3)y - 3 = -\frac{4}{3}(x + 3)

  3. Simplify the equation: Expand the right-hand side: y3=43x4y - 3 = -\frac{4}{3}x - 4 Add 3 to both sides to isolate yy: y=43x1y = -\frac{4}{3}x - 1

    So, the equation of line tt is: y=43x1y = -\frac{4}{3}x - 1

Final Answer:

The equation of line tt is: y=43x1y = -\frac{4}{3}x - 1
