Answer: -5x= -11
Step-by-step explanation:
Use the formula
y+2=-5/7(x+1)
solve and you will get the equation which is
f(x)=-5/7(x)-19/7
The y axis is the heart rate so for the first one it is 121 then for the x axis which is age it will be 55.For second the heart rate is less than 198 and 90 for age
