Can i have brainliest
Answer:
-9
Step-by-step explanation:
3x + 1 = x -17
3x-x=-17-1
x = -9
Point slope is nicer
y-y1=m(x-x1)
goes through the point (x1,y1) and has a slope of m
slope itnercept
y=mx+b
m=slope
b=y intercept
first find slope
slope between 2 points (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(7,82) and (4,18)
slope=(18-82)/(4-7)=-64/-3=64/3
point slope
point is (7,82) or you can do (4,18)
I'll do both
y-82=(64/3)(x-7) or
y-18=(64/3)(x-4)
those both work
slope intercept
slope is 64/3
y=64/3x+b
find b
input a point
(4,18)
18=64/3(4)+b
18=256/3+b
minus 256/3 from both sides
note: 18=54/3
-202/3=b
y=64/3x-202/3 is equation in slpe intercept
