find the equation of straight line which passes through the point of intersection of straight lines.x+2y+3=0 and 3x+4y=7 and par

erastovalidia [21]

Answer:

Equation of the line in question: $y = x - 21$ .

Step-by-step explanation:

Start by finding the intersection of the two straight lines. The equation for both lines shall hold at their intersection. (Using the idea of the Gaussian Elimination.)

$\left\{\begin{aligned}&x + 2y =-3\\&3x + 4y=7\end{aligned}\right.$ .

Add -3 times the first equation to the second:

$\left\{\begin{aligned}&x + 2y =-3\\& -2y=16\end{aligned}\right.$ .

Add the second equation $-2y=16$ to the first:

$\left\{\begin{aligned}&x = 13\\&y=-8\end{aligned}\right.$ .

Hence the intersection of the two lines will be $(13, -8)$ .

Now, find the slope of that straight line. $y - x = 8$ is equivalent to $y = x +8$ . The slope of that line is equal to 1. So will be the slope of the line in question.
