Answer:
y=.5x-2
Step-by-step explanation:
If one line is perpendicular to another that means that their slopes are negative reciprocals
which means that the slope (or m in y=mx+b) is .5
so far we have
y=.5x+b
to solve for b we plug in (8,2)
2=.5(8)+b
2=4+b
-2=b
therefore our equation is
y=.5x-2
Answer:
rate=55 percent
Step-by-step explanation:
SI=PRT
p=90
r=?
t=2
si=99
R=SI÷PT
R=99÷90×2
r=99÷180=0.55
r=0.55×100
R=55%

Answer:
(C) 1/3
Step-by-step explanation:
The slope intercept form: y = mx + b.
Note:
m = slope
b = y-intercept
x & y = (x , y) for the points.
You are trying to get the y-intercept of the following function given:
f(x) or y = (-2/9)x + (1/3)
1/3 is your answer, or (C), for 1/3 replaces the <em>b</em> inside the equation.
If you really need the slope, the slope of the following equation is (-2/9), which replaces the <em>m</em> inside the equation.
