Write an equation of a line perpendicular to y =
x - 5 in slope-intercept form that passes through the point (2, -7).

y = x - 5, with slope, or m of 1
Slope of equation of line that's perpendicular to line with equation: y = x - 5:
With m, or slope being - 1, and point (2, - 7), using the point-slope formula: ,
we get:
y + 7 = - x + 2
y = - x + 2 - 7
Equation:
