Answer:
Step-by-step explanation:
1. Find the slope:
7 -3/ 1 + 1 = 4/2 = 2 = m
2. Find b by plugging in the m and one of the points given into y = mx + b
7 = 2 ( 1 ) + b
7 = 2 + b
5 = b
3. Write the equation using the m and the b you just found
y =2 x + 5
200- your age = your target heart rate.
Hence, for a 40 year old man, it’s 200-40= 160.
Hope this helps!
