Question 1:   Rewrite the equation of a straight line in the slope- intercept form: $x+2y+1=0$
$y=\frac{x+1}{2}$
$y=-\frac{1}{2}x-1$
$y=-2x-1$
$y=-\frac{1}{2}x-\frac{1}{2}$
Question 2:   Rewrite the equation of a straight line in a standard form: $y=\frac{1}{3}x-1$
$3x+y-1=0$
$x+3y-1=0$
$x-y-3=0$
$x-3y-3=0$
Question 3:   Find the equation of a straight line going through the points $A\left(2,5\right)$ and $B\left(3,8\right)$
$y=2x-3$
$y=3x-1$
$y=-3x+1$
$y=2x+5$
Question 4:   Find the equation of a straight line going through the points $A\left(-1,4\right)$ and $B\left(2,2\right)$
$y=-\frac{1}{3}x+2\frac{2}{3}$
$y=-\frac{1}{2}x+2$
$y=\frac{1}{2}x+4\frac{2}{3}$
$y=-\frac{2}{3}x+3\frac{1}{3}$
Question 5:   Find the equation of a straight line if it crosses $x$ - axis at $-1$ and $y$ -axis at $2$
$y=2x+2$
$y=x+2$
$y=-x+2$
$y=2x-1$
