It is not possible to draw a graph on this site.
You can write this question as:
F = 2 C + 30
where
F = temperature [°F]
C = temperature [°C]
Draw a Cartesian coordinate system.
Mark the horizontal axis with C and the vertical axis with F
Now calculate:
F = 0
2 C + 30 = O
2 C = - 30
C = - 30 / 2 = - 15
and
C = 0
F = 2 • 0 + 30 = 30
In Cartesian coordinate system drav points:
C = - 15 , F = 0
( - 15 , 0 )
and
F = 30 , C = 0
Draw a straight line through these two points.
That is a conversion graph.
Read on graph:
25° C = 80° F
100°F = 35°C
0°C = 30°F
200°F = 85°C
You can roughly convert temperature in degrees Celsius to degrees
Fahrenheit by doubling the degrees Celsius and adding 30.
Draw a conversion graph up to 50 °C. Use your graph to estimate the
following:
a the temperature in °F equivalent to 25°C,
b the temperature in °C equivalent to 100 °F,
c the temperature in °F equivalent to 0°C,
d the temperature in °C equivalent to 200 °F
