Answer:
A
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
Therefore:
(-3-(-4))/(-5-1)
-1/6 (A)
Answer:
y=1/2x+5
Step-by-step explanation:
Plug it into the formula for a point and a slope.
(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))
Y-8=1/2(x-6)
Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.

ax+r=7
Move ax to the other side. +positive ax changes to -negative ax
ax-ax+r=7-ax
r=7-ax
Answer: r=7-ax or r=-ax+7 ( same thing) but rearranged
