Math Problem Statement

Create an equation for a line that is parallel to the line y = 3/2x + 4 and passes through the point (-4, 10).

Solution

The problem asks for an equation of a line that is parallel to the given line y=32x+4y = \frac{3}{2}x + 4 and passes through the point (4,10)(-4, 10).

Step-by-Step Solution:

  1. Identify the slope: The slope of the given line y=32x+4y = \frac{3}{2}x + 4 is m=32m = \frac{3}{2}. Since parallel lines have the same slope, the slope of the new line will also be 32\frac{3}{2}.

  2. Use point-slope form: The equation of a line in point-slope form is: yy1=m(xx1)y - y_1 = m(x - x_1) Here, m=32m = \frac{3}{2}, and the point (x1,y1)=(4,10)(x_1, y_1) = (-4, 10).

    Substituting the values: y10=32(x+4)y - 10 = \frac{3}{2}(x + 4)

  3. Simplify the equation: Distribute the slope on the right-hand side: y10=32x+32×4y - 10 = \frac{3}{2}x + \frac{3}{2} \times 4 y10=32x+6y - 10 = \frac{3}{2}x + 6 Now, add 10 to both sides to solve for yy: y=32x+6+10y = \frac{3}{2}x + 6 + 10 y=32x+16y = \frac{3}{2}x + 16

Final Equation:

The equation of the line that is parallel to y=32x+4y = \frac{3}{2}x + 4 and passes through the point (4,10)(-4, 10) is: y=32x+16y = \frac{3}{2}x + 16
