They both are linear because they are in slope-intercept form
Answer:
P(d) = 62 - 2d
Step-by-step explanation:
P = pound per square inch
d = days
(52 - 46) / 3 = 2
46 + 2 * 8 = 62
In the question, they GIVE you the equation for the line:
y = 1.1 x + 1.37 .
When you look at the graph, you notice that the numbers
are actually thousands, so the equation is really
y = (1.1 thousand) x + (1.37 thousand)
or
y = 1,100 x + 1,370 .
The slope of the line is 1,100 .
Choice 'C' says that, because
the slope of any graph = (change in 'y') / (change in 'x') .
