Question 71084This question is from textbook
: write the slope intercept form for an equation of the line perpendicular to the graph of the given equation and passing through the given point?
2x-7y=1, (-4,0) This question is from textbook
You can put this solution on YOUR website! 2x-7y=1
y=2x/7-1/7 the given line has a slope of 2/7.
therefore the perpendicular lines slope is the negative reciprical (-7/2)
now replace the x & y values in the line equation y=mx+b with (-4,0) & sole for the y intercept (b)
b=-14 thus the equation of the perpendicular line is
here are the two libnes plotted
