Math Problem Statement

Use point-slope form to write the equation of a line that passes through the point left parenthesis, 16, comma, minus, 1, right parenthesis(16,−1) with slope 33.

Solution

The point-slope form of a line's equation is given by:

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 of the line.

Given:

  • (x1,y1)=(16,1)(x_1, y_1) = (16, -1),
  • m=33m = 33,

Substitute the values into the formula:

y(1)=33(x16)y - (-1) = 33(x - 16)

Simplifying:

y+1=33(x16)y + 1 = 33(x - 16)

Now distribute the 33 on the right side:

y+1=33x528y + 1 = 33x - 528

Finally, subtract 1 from both sides to solve for yy:

y=33x529y = 33x - 529

So, the equation of the line is:

y=33x529y = 33x - 529
