11.
slope intercept is solve for y
12x+y=-5
y=-12x-5
12. y-y1=m(x-x1)
a point is (x1,y1) and slope is m
y+2=(-2/3)(x+3)
y+2=(-2/3)x-2
y=(-2/3)x+0
13.
slope find
(-1-2)/(-5-0)
-3/-5=3/5
given (0,2)
yint is 2
y=mx+b
b=yint
y=(3/5)x+2
14.
initially (x=0) y intercept is 9
speed is slope is -6 because getting close to home
y=-6x+9
a. standard form is solve for constant
6x+y=9
b. y intercpet is 9 that is how far you are away from home at start
c. x intercept is where y=0 or when you reach home
that is
0=-6x+9
6x=9
x=3/2
at 3/2 hours or 1.5hours
The variable part of the answer would be xy because variables are the letters in the equation. So, as x and y are the letters in the equation, they would be the variable
What's a firest? And whats the question?
