Question 261891: Write an equation in Standard form using only intergers for the line described.
A line perpendicular to y=2/3x+5 (2,-3)
my start: y-(-3)=-3/2(x-2) (the correct answer is 3x+2y=0 but I can't get there)
You can put this solution on YOUR website! A line perpendicular to y=2/3x+5 (2,-3)
(y = (2/3)x + 5 would be better)
The slope of the given line is 2/3
Lines perpendicular to it have a slope of -3/2, the negative inverse.
----------------
Find the equation of the line thru (2,-3) with a slope of -3/2.
Use y = mx + b and the point to find b:
-3 = (-3/2)*2 + b
b = 0
--> y = -3x/2
You can put this solution on YOUR website! First, the slope, m, of a line that is perpendicular to the given line is the negative reciprocal of the slope of the given line.
The slope of the given line is .
The slope of the new line will be so you can start with the slope-intercept form: but substitute Now substitute the x- and y-coordinates from the given point (2, -3) to find the value of b, the y-intercept. Now you can finish the equation in slope-intercept form: But you want integers only, so multiply through by 2 to get: Finally, add 3x to both sides to get the standard form.
