Question and answer
Is the line through points P(–8, –10) and Q(–5, –12) perpendicular to the line through points R(9, –6) and S(17, –5)? Explain.
No, they are not perpendicular because they don't have the same slopes.

Plans for a bridge are drawn on a coordinate grid. One girder of the bridge lies on the line y = –9x – 9. A perpendicular brace passes through the point (–1, 7). Write an equation of the line that contains the brace.
Weegy: First: place the equation in the slope-intercept form which is, y = mx+b > subtract "9x" from both sides (when you move a term to the opposite side, [ [ always use the opposite sign). 9x - 9x + 3y = - 9x + 6 3y = - 9x + 6 *ISolate the "y" variable on one side - divide each term by 3. 3y/3 = - 9x/3 + 6/3 y = - 9x/3 + 6/3 y = - 3x + 2 *Identify the slope which is, -3 (a whole number/fraction beside the x-variable) & a line parallel to the line has the same slope. Sec: place the slope (-3) & the point in the point-slope formula which is, y - first y = m(x - first x) y - 3 = - 3(x - 5) y - 3 = - 3x - 3(-5) y - 3 = - 3x - (-15) y - 3 = - 3x + 15 Third: isolate the y-variable on one side - add 3 with both sides. y - 3 + 3 = - 3x + 15 + 3 y = - 3x + 15 + 3 y = - 3x + 18 ] ] (More)

how do you symplify 8 over -14?
Weegy: (8)/(-14) Move the minus sign in the denominator to the front of the expression. -(8)/(14) Reduce the expression -(8)/(14) by removing a factor of 2 from the numerator and denominator. -(4)/(7) (More)
