Answer:
m=3
Explanation:
slope=m=y2-y1/x2-x1
(29,97),(18,64) for given points
m=64-97/18-29 ⇒ m=-33/-11
m=3
b): 97/29 ,64/18,-14/-8, 52/14,-71/-27
No, it does not matters which points you take to calculate the slope because at each point m=3
for points (18,64) and (-8,-14)
m=-14-64/-8-18
m=-78/-26
m=3
for points:(-8,-14) and (14,52)
m=52+14/14+8
m=66/22
m=3
for points (14,52) and (-27,-71)
m= 3
write the equation of a line at a point (-8,-14)
the equation of a line: y=mx+b
y=-14 , x=-8 , m=3, find b
-14=3(-8)+b
-14=-24+b
b=-14+24
b=10
the equation : y=3x+10
