Answer:
y+2 =3(x+1)
Step-by-step explanation:
Firstly I will find slope of this linear function:
m=(y-yo) / (x-xo)
m=(-2-10)/(-1-3)
m=-12/-4
m=3
Replacing A(-1-2) :
(y-yo)=m(x-xo)
The age of a person whose maximum pulse is 152 is 30 years old.
Answer: All points in the shaded region after 2y<-12x+4 is the solution.
Step-by-step explanation:
Since we have given that

We need to find the point of solution to the system of inequalities:
Suppose

We first check the consistency of the system of equation:

So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.
Using zero test,

0<4 it is true so, shaded part is towards the center.
Similarly,

0<4 again it is true it would be shaded towards the center.
So, the common part will be after 2y<-12x+4 .
Hence, all the points in the shaded region is the solution.
