Math Problem Statement

Find the equation of the line passing through the points (5, -9) and (3, -2).

Solution

The problem shows two points, (5,9)(5, -9) and (3,2)(3, -2). I will assume you are asking to find the equation of the line passing through these points or the slope. Let me proceed with the slope calculation and equation derivation:

Step 1: Calculate the slope (mm):

The slope formula is: m=y2y1x2x1m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the points (x1,y1)=(5,9)(x_1, y_1) = (5, -9) and (x2,y2)=(3,2)(x_2, y_2) = (3, -2): m=2(9)35=2+92=72=72m = \frac{-2 - (-9)}{3 - 5} = \frac{-2 + 9}{-2} = \frac{7}{-2} = -\frac{7}{2}

Step 2: Write the equation of the line (y=mx+by = mx + b):

We use the point-slope form of the equation: yy1=m(xx1)y - y_1 = m(x - x_1)

Substituting m=72m = -\frac{7}{2}, and using (x1,y1)=(5,9)(x_1, y_1) = (5, -9): y(9)=72(x5)y - (-9) = -\frac{7}{2}(x - 5) y+9=72x+352y + 9 = -\frac{7}{2}x + \frac{35}{2}

Simplify: y=72x+3529y = -\frac{7}{2}x + \frac{35}{2} - 9 y=72x432y = -\frac{7}{2}x - \frac{43}{2}

Final Equation:

y=72x432y = -\frac{7}{2}x - \frac{43}{2}
