Find the equation of the line which passes through the point (1,2), and is perpendicular to the line with the equation y=−12x+5.

malfutka [58]

12y = x + 23

Step-by-step explanation:

y = −12x + 5
Perpendicular slopes are opposite reciprocals.
The original slope is −12
So the new perpendicular slope is 1/12.
We plug the point (1, 2) and the slope m = 1/12 into the slope intercept form of the equation y = mx + b

y = mx + b

2 = 1/12 * 1 + b

2 = 1/12 + b

b = 23/12

When we simplify this, we arrive at 12y = x + 23

Graphing<br>solve a system of equation by graphing

Alex787 [66]

SOLUTION:

$Point \ (1,3)$

<h2>Explanation:</h2>

Let's use the following System of Linear Equations in Two Variables in order to solve this exercise:

$\begin{array}{c}(1)\\(2)\end{array}\left\{ \begin{array}{c}y=2x+1\\y=-4x+7\end{array}\right.$

So we can graph these lines using two points.

For eq (1):

$y=2x+1 \\ \\ If \ x=0 \ then \ y=2(0)+1 \therefore y=1 \\ \\ If \ y=0 \ then \ 0=2x+1 \therefore x=-\frac{1}{2} \\ \\ \\ Points: \\ \\ (0,1) \\ \\ (-\frac{1}{2},0)$

So graph a line that passes through these two points. This is the red line shown below.

For eq (2):

$y=-4x+7 \\ \\ If \ x=0 \ then \ y=-4(0)+7 \therefore y=7 \\ \\ If \ y=0 \ then \ 0=-4x+7 \therefore x=\frac{7}{4} \\ \\ \\ Points: \\ \\ (0,7) \\ \\ (\frac{7}{4},0)$

So graph a line that passes through these two points. This is the blue line shown below.

<em>The solution of this system of equation is the point of intersection, which is (1,3)</em>
