\(\left(\frac{3}{5},\frac{5}{2}\right)\)
\(\left(\frac{2}{5},\frac{2}{5}\right)\)
\(\left(\frac{3}{5},\frac{3}{5}\right)\)
\(\left(\frac{2}{5},\frac{3}{5}\right)\)
7.
Equation of the straight line perpendicular to the line x - y + 5 = 0, through the point of intersection the y-axis and the given line
x - y - 5 = 0
x + y - 5 = 0
x + y + 5 = 0
x + y + 10 = 0
8.
The coordinates of the four vertices of a quadrilateral are (-2, 4), (-1, 2), (1, 2) and (2, 4) taken in order. The equation of the line passing through the vertex (-1, 2) and dividing the quadrilateral in the equal areas is
x + 1 = 0
x + y = 1
x + y + 3 = 0
x - y + 3 = 0
9.
The slope of the line which makes an angle 45o with the line 3x- y = -5 are:
1, -1
\(\frac{1}{2},-2\)
\(1,\frac{1}{2}\)
\(2,-\frac{1}{2}\)
10.
Which of the following equation is the locus of (at2, 2at)
\(\frac{x^2}{a^2}-\frac{y^2}{b^2}=1\)
\(\frac{x^2}{a^2}+\frac{y^2}{b^2}=1\)
x2 + y2 = a2
y2 = 4ax

\((p+2 q) x+(p-3 q) y-p+q=0 \)
\(p(x+y-1)+q(2 x-3 y+1)=0 \)
\(x+y=1 ...(1)\)
\(2 x-3 y=-1..(2)\)
\(\begin{array}{r} 3 \times(1) \Rightarrow 3 x+3 y=3 \\ (2) \Rightarrow 2 x-3 y=-1 \\ \hline 5 x=2 \end{array}\)
\(x=\frac{2}{5}, y=\frac{3}{5} \)
\(\therefore\left(\frac{2}{5}, \frac{3}{5}\right) \)
7.
x - y + 5 = 0;
Put x = 0, then y = 5
The point is (0, 5)
Any line perpendicular to x - y + 5 = 0 is
x + y + k = 0,
This passes through (0, 5)
k = -5
Required equation is x + y - 5 = 0
8.
The point M is (0, 3)
The equation of line joining ('-1, 2) and (0, 3) is
\(\frac{y-2}{3-2} =\frac{x+1}{0+1} \)
\(x-y+3 =0\)
9.
\(\text { Slope of } 3 x-y+5=0 \text { is } \frac{-3}{-1}=3=m_{1}\)
Let m2 be the slope of the second line
\(\text {Given } \tan \theta=\tan 45^{\circ}=1 \Rightarrow \frac{m_{1}-m_{2}}{1+m_{1} m_{2}}=\pm 1\)
\(\frac{3-m_{2}}{1+3 m_{2}}=1 \quad \frac{m_{2}-3}{1+3 m_{2}}=1\)
\(3-m_{2}=1+3 m_{2} \quad m_{2}-3=1+3 m_{2}\)
\(2=4 m_{2} \quad-2 m_{2}=4\)
\(\mathrm{m}_{2}=\frac{1}{2} \quad \mathrm{~m}_{2}=-2\)
\(\left(\frac{1}{2},-2\right)\)
10.
\(\left(a t^{2}, 2 a t\right) \Rightarrow x=a t^{2}, \quad y=2 a t\)
\(y^{2} =4 a^{2} t^{2} \)
\(=4 a^{2}\left(\frac{x}{a}\right) \)
\(y^{2} =4 a x \)
