Answer:
see below
Explanation:
there are 3 points given
diff in y / diff in x = slope
so plug in any 2 points' Y and x and get the slope
because it's downward shaped, you know the slope MUST be negative.
so diff in Y = 23-29 = -6
diff in X = 3-7 =2
so slope is +3
intercept is given, when x=0 y = 32
it represents what F is when it's 0C°
