Question 655155
Write the standard form of the equation of the line with a slope 2/7 passing through the point (7, -4)
.
plug into "point-slope" form:
y - y1 = m(x - x1)
y - (-4) = (2/7)(x - 7)
y + 4 = (2/7)x - 2
y = (2/7)x - 6
.
A line (L1) has a slope of 1. The line through which of the following points is perpendicular to L1?
