Find the slope \( m \) of the line through the following pair of points and draw the line through the points. \( (3,-1),(-2,-2) \) Answer exactly. \( m= \)

Problem 4: A curve has a focus at \( (-1,1) \), the equation of its corresponding directrix is \( x+y+1=0 \) and the curve passes through the point \( (0,1) \). Is this curve parabola, ellipse or hyperbola?

A circle's area is given as \( 78.54 \) square centimeters. What is the radius of the circle?

gh the given point. 4. perpendicular to \( y=3 x-2 \) through \( (6,-1) \)

7 Point \( B \) lies on \( \overline{A C} \) between \( A \) and \( C \). If \( A B=8 \) and \( A C=10 \), find \( B C \).

\( 6321 km = \sqrt { x ^ { 2 } + 3500 ^ { 2 } km + z ^ { 2 } } \)
