The slope of a line is –4 and its y-intercept is (0, 4). What is the equation of the line that is perpendicular to the first line and passes through (–8, 2)?
Weegy: The slope of a line is 4 and its y-intercept is (0, 4). The equation of the line that is perpendicular to the first line and passes through ( 8, 2) is y = 1/4x + 4. User: A line passes through the point (–2, 4), and its y-intercept is (0, –6). What is the equation of the line that is perpendicular to the first line and passes through the point (5, –4)? Weegy: The slope of a line is 4 and its y-intercept is (0, 4). The equation of the line that is perpendicular to the first line and passes through ( 8, 2) is y = 1/4x + 4. User: A line passes through the point (–2, 4), and its y-intercept is (0, –6). What is the equation of the line that is perpendicular to the first line and passes through the point (5, –4)? Weegy: The slope of a line is ?4 and its y-intercept is (0, 4). The equation of the line that is perpendicular to the first line and passes through (?8, 2) is y = 1/4x + 4. (More)

Solve the system of equations. 8x – 3y = 1 –2x + 3y = 11 A. (–1, –3) B. (–1, 3) C. (2, 5) D. (5, 2)
Weegy: 8x – 3y = 1 2x + 3y = 11 Adding up the two equations the result is: 6x = 12 x = 2; 8(2) - 3y = 1 -3y = 1 - 16 = -15 y = 5, The solution for the system of equations 8x – 3y = 1 2x + 3y = 11 is: (2, 5) User: Which of the following would be the best first step to solve the system of equations? 2x – 9y = 6 4x – 3y = –7 A.
