Answer 1

Answer:

Perpendicular lines means negative reciprocal slopes.

So you know the slope, m2, of line2, if line 1 is y=1/4x-10 (I think that there was a typo here at the second equals sign), with a slope of 1/4, m1, is m2 = -4.

These slopes can be understood by looking at the lines in slope intercept, y=mx+b, form where m is the slope and b is the y coordinate of the point where the line crosses the y axis.

So our desired perpendicular line, line2, can be written as y = m2*x + b, or y = -4x + b. But we are also given that line2 passes through the point (5,7), so we can put 7 and 5 into our equation, for y and x respectively, and figure out what b is an voila! We have line2.
