You can put this solution on YOUR website! Write the slope intercept form of the equation of the line described.
through (2,-5) and perpendicular to y=2/7x+1
**
Equation of a line: y=mx+b, m=slope, b=y-intercept
For given equation: y=2/7x+1
slope=2/7
slope of perpendicular line=-7/2 (negative reciprocal)
Equation of perpendicular line:
y=-7x/2+b
find b using coordinates of given point (2,-5)
-5=-7*2/2+b
b=-5+7=2
equation: y=-7x/2+2
