what is the formula
Answered by GPT 3.5
Since line j is perpendicular to line k, the slope of line j will be the negative reciprocal of the slope of line k. The negative reciprocal of -5 is 1/5.

We know that line j passes through the point (5, 9). We can use the point-slope form of a linear equation to write the equation of line j.

The point-slope form is given by: y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope.

Substituting the given values, we get:
y - 9 = (1/5)(x - 5)

Simplifying the equation gives us the final equation for line j:
y - 9 = (1/5)x - 1

Rearranging the equation to the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept, we have:
y = (1/5)x + 8

The formula to find the equation of a line is the point-slope form:

y - y₁ = m(x - x₁)

Where:
- (x₁, y₁) is a point on the line
- m is the slope of the line

By substituting the given values into this formula, we can find the equation for line j.
