Math Problem Statement

write the equation in point-slope form of the line that passes through the given point with the given slope: (-3, -5); m = -2

Solution

The point-slope form of a linear equation is:

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

Where:

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

In this case, the point is (3,5)(-3, -5) and the slope m=2m = -2.

Substituting these values into the formula:

y(5)=2(x(3))y - (-5) = -2(x - (-3))

Simplifying:

y+5=2(x+3)y + 5 = -2(x + 3)

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