What is the equation of the line that passes through the point (5,0) and has a slope of -1

Answer 1

equation of line is y = mx + b, where m is slope and b is y-intercept.

since slope is -1, m = -1. Since line passes through (5,0), we substitute 5 for x and 0 for y (along with -1 for m) to solve for b:

0 = -5 + b ---> b = 5

so equation is y = -x + 5
