Accepted Solution

A:
Answer: The point slope form of the line that passes through (-8,2) and is parallel to a line with a slope of -8 is 8x + y + 62 = 0 Solution: The point slope form of the line that passes through the points [tex]\left(x_{1} y_{1}\right)[/tex] and parallel to the line with slope β€œm” is given as Β [tex]y-y_{1}=m\left(x-x_{1}\right)[/tex] --- eqn 1 Where β€œm” is the slope of the line. Β  [tex]x_{1} \text { and } y_{1}[/tex] are the points that passes through the line. From question, given that slope β€œm” = -8 Given that the line passes through the points (-8,2).Hence we get [tex]x_{1}=-8 ; y_{1}=2[/tex]By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -8 can be found out. y-2=-8(x-(-8)) On simplifying we get y – 2 = -8(x +8) y – 2 = -8x -64 y – 2 +8x +64 = 0 8x + y +62 = 0 Hence the point slope form of given line is 8x + y +62 = 0
