Math Problem Statement

What is the equation of the line that passes through the point (-8, 4) and has a slope of -1/2?

Solution

It seems like you're working on a problem involving the equation of a line in point-slope form. The task is asking for the equation of a line that passes through the point (8,4)(-8, 4) and has a slope of 12-\frac{1}{2}.

To find the equation, you can use the point-slope form of a line equation:

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

Where:

  • mm is the slope,
  • (x1,y1)(x_1, y_1) is a point on the line.

Given the slope m=12m = -\frac{1}{2} and the point (8,4)(-8, 4), substitute these values into the point-slope form:

y4=12(x+8)y - 4 = -\frac{1}{2}(x + 8)

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

Would you like to simplify this or solve for yy? Let me know if you need further details!
