1/2, line rises
we are given the following pair of points and and we are to find the slope of line passing through these points:
(-1, 3) and (3, 5)
slope = = = =
the slope of this line is 1/2 which is positive so the line rises from bottom left towards top right.
to start, we know that the initial boiling point is 212 degrees f. for every 1 added to e, the boiling point decreases by 2. so, we havethe equation 212 - 2e or -2e + 212 = b or d).
i believe the answer is 9, but i'm not sure.
(if i can i have brainliest pls? )
