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.
Multiply the first equation by 4.
B.
Multiply the second equation by 2.
C.
Multiply the first equation by –3.
D.
Multiply the second equation by –3. (More)
