Answer:i think it is y-y1=m(x-x1)
m is herein undefined.
Slope, m, is defined as change-of-y divided by change-of-x...
m=(y-y1)/(x-x1)
The mathematical concept of undefined means that the denominator is zero. This means that both values of x are equal.
(-4,-8)
This equation is x=-4
It is a vertical line and includes the point of y=-8.
Step-by-step explanation:
M = miles Marcos drove
c = miles Candice drove
m = 2c
m + c = 66
Plug m=2c into the second equation :
m + c = 66
(2c) + c = 66
3c = 66
