Answer:
x = - 4
Step-by-step explanation:
x = 19 is a vertical line parallel to the y- axis
A line parallel to it has the equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 4, 7 ) with x- coordinate - 4 , then
x = - 4 ← equation of parallel line
In this case the temperature depends on the hour. So temperature is your X and hour is your Y variable. When h=0, x=0. So the 21*C is you x=0 or y-int point.
If we are trying to match the equation for a line of y=mx+b, 21*C=b.
Our rate of change is -4*C/h, which is our m variable.
So y=(-4)x+(21)
OR in this case, t=-4h+21.
