Step-by-step explanation:
if 'c' is meant to be another 'x' the answer is
(3, 1)
x = 3,y = 1
4. Normal body temperature is 98.6 degrees Fahrenheit, although it varies slightly for some people. Someone ?
Answer: y= 3x - 
Step-by-step explanation:
Since we know the slope and a set of coordinates we can insert them into the formula y=mx+b and find what b is.
y=mx+b
-1/2=3(2)+b
-1/2=6+b
-1/2-6=6-6+b
-6 1/2=b
Therefore the equation is y=3x -
