Can I please have some help with math

Which is a solution to the equation 6x + y = –4?
A.(1, 2)
B.(1, –10)
C.(2, 8)
D.(2, –8)

What is the slope of the graph of 8x – 4y = 11?
A.–2
B.–½
C.½
D.2
What is the slope of the line that passes through the points (–1, 13) and (4, –2)?
A.–3
B.-1/3
C.3
D.The slope is undefined.

y = -6x - 4
B.(1, –10)

4y = 8x - 11
y = 2x - 11
m = 2
D.2

m = (y2 - y1)/(x2 - x1) = (-2 - 13)/(4 + 1) = -15/5 = -3
A.–3
