Answer:
Step-by-step explanation:
a) the given equation is expressed as
y = - x + 56
b) we will substitute the given values for x into the equation to determine the corresponding values for y. Therefore,
When x = 0,
y = - 0 + 56
y = 56
When x = 5,
y = - 5 + 56
y = 51
When x = 10,
y = - 10 + 56
y = 46
c) For the scale to be used on the graph,
Let 2 cm represent 10 units on the x axis.
Let 2 cm represent 10 units on the y axis
The y axis represents temperature.
The x axis represents the number of hours
