Answer :
Answer:
b = 59
Step-by-step explanation:
Since table attached in the picture shows the linear relationship,
Equation showing the relationship between the altitude (x) and temperature (y) will be in the form of y = mx + b.
Where m = slope of the line
b = y-intercept of the line
y-intercept of a line means "y-value at x = 0"
For x = 0,
y = m(0) + b
y = b
From the table attached,
at x = 0, y-value = 59°F
Therefore, y-intercept 'b' = 59 will be the answer.
