Question

write an equation in slope-intercept form of a line containing the points (-8,9) and (-6,-5)
a) y=x-11
b)y=-7x+37
c)y=-7-47
d)y=-x-1

Answer 1

m=14/-2=-7
y=-7x+7(-6)-5=-7x-47

Answer 2

\[\frac{y_2-y_1}{x_2-x_1}=\frac{9-(-5)}{-8-(-6)}=\frac{9+5}{-8+6}=\frac{14}{-2}=-7\]

Answer 3

so the answer s not in the selection..
to get the slope m=(y2-y1)/(x2-x1)

Answer 4

i guess x is missing in option c

Answer 5

\[y-9=-7(x-(-8))\]
\[y-9=-7(x+8)\]
\[y-9=-7x-56\]
\[y-9=-7x-49\]

Answer 6

oops

\[y=-7x-47\]
uzma way snappier!
