The 2 is the hundreds and 8 is the thousands
If f(-2)=1 and f(1) = 7, then 2 pts on the str. line are (-2,1) and (1,7).
7 - 1
The slope of the line connecting these 2 pts is m = ---------- = 6/3 = 2
1-(-2)
Use the slope-intercept formula. Let the point be (1,7) and the slope be 2:
7 = 2(1) + b; find the y-intercept, b:
7 = 2 + b, so b = 5, and the equation of this line through the 2 given points is then
y = 2x + 5 (answer)
Answer:
y= (-1)*x
Step-by-step explanation:
lets assume that the line equation is
y=m*x +b
where m is the slope and b the independent variable that intercept Y axis.
then replacing the value of m:
y=(-1)*x + b
after that we have to look for the value of b. Its obtained replaicing the given point (8,-8):
-8 = (-1)*(8) +b
-8 = -8 + b
0 = b
Therefore the equation of the line is:
y= (-1)*x
X(1/2) = 12
x(1/2)(2) = 12(2)
x(1) = 24
x = 24
hope this helps
