Explanation:

Convert the equation to steep intercept kind to gain *y* = –1/3*x* + 2. The old slope is –1/3 and also the new slope is 3. Perpendicular slopes have to be the contrary reciprocals of every other: *m*1 * *m*2 = –1

With the new slope, use the slope intercept kind and the allude to calculate the intercept: *y* = *mx* + *b* or 5 = 3(1) + *b*, therefore *b* = 2

So *y* = 3*x* + 2

What heat is perpendicular come

and also passes through ?Explanation:

Convert the provided equation come slope-intercept form.

You are watching: Which of the following lines is perpendicular to y=-2x+3

The steep of this heat is

. The steep of the heat perpendicular come this one will have actually a slope equal to the negative reciprocal.The perpendicular slope is

.Plug the new slope and also the given suggest into the slope-intercept form to find the y-intercept.

So the equation that the perpendicular line is

.What is the equation the a line that runs perpendicular come the heat 2*x* + *y *= 5 and passes with the point (2,7)?

Explanation:

First, put the equation the the line given into slope-intercept type by fixing for *y*. You gain *y* = -2*x* +5, so the slope is –2. Perpendicular lines have actually opposite-reciprocal slopes, so the steep of the line we want to uncover is 1/2. Plugging in the suggest given right into the equation *y* = 1/2*x* + *b* and solving because that *b*, we acquire *b* = 6. Thus, the equation that the line is *y* = ½*x* + 6. Rearranged, the is –*x*/2 + *y* = 6.

Line *m *passes v the clues (1, 4) and also (5, 2). If heat *p *is perpendicular to *m, *then i beg your pardon of the following might represent the equation for *p?*

Explanation:

The steep of *m* is same to y2-y1/x2-x1 = 2-4/5-1 = -1/2

Since line *p* is perpendicular to line *m*, this method that the commodities of the slopes the *p* and also *m* have to be **–**1:

(slope that *p*) * (-1/2) = -1

Slope that *p* = 2

So we must choose the equation that has actually a steep of 2. If we rewrite the equations in point-slope kind (y = mx + b), we view that the equation 2x **–** y = 3 might be created as y = 2x – 3. This method that the steep of the heat 2x **– **y =3 would certainly be 2, therefore it could be the equation of line *p*. The price is 2x – y = 3.
