write an equation of the line that passes through the point (8, -1) and is perpendicular to the line pictured

Answer 1

Determine the slope of the line (not) pictured. The line that is perpendicular will have a slope that is the negative reciprocal of that line.

Equation of line is y = mx + b, where (x,y) is point line passes through and m equals slope.

Using the slope determined plus (8,-1) for (x,y) to solve for b, the y-intercept to have the equation of the line.
