D. x = 5

User: Which choice is the equation of a line that passes through the point (–2, 8) and is perpendicular to the line represented by this equation?
5x - 2y = -10
A. 2x- 5y = 26
B. 5x + 2y = 10
C. 2x + 5y = 36
D. -2x + 5y = -13

Which choice could be the equation of a line parallel to the line represented by this equation?
3x- 2y = 6

Weegy: 2(2x/3 + 7) - 3 = 5x 4x/3 + 14 - 3 = 5x 11 = 11x/3 x = 3 y = 2(3)/3 + 7 = 9 x(y) = 3(9) = 18. Answer is d. chikaygoods|Points 250|

x = 5 could be the equation of a line perpendicular to the line represented by this equation of y = 5 . If y = 5 ,the slope is 0 , the slope of the line perpendicular to it is undefined .

2x + 5y = 36 is the equation of a line that passes through the point (–2, 8) and is perpendicular to the line represented by this equation of 5x - 2y = -10 . 5x - 2y = -10; 2y = 5x + 10; y = 5/2x + 5 ; The slope of 5x - 2y = -10 is 5/2 , slope of the line is -2/5, so the line is as follows ; y - 8 = -2/5(x + 2); 5y - 40 = -2x - 4; 2x + 5y = 36 .

The equation of a line that passes through the point (0, –15) and is parallel to the line represented by this equation of 5x- 4y = 12 is y = 5/4x - 15 .
