Answer: The answer is (c) across many years.
Step-by-step explanation: We are given four options out of which we are to select the one correct information that a line graph shows.
A line graph means a linear relation between any two unknown variables. If one unknown variable is the number of years, then the graph can show a relation between the number of years with any information like growth of some person, place or thing.
Therefore, a line graph can show information across many years.
Thus, (c) is the correct option.
Draw the line y=x. It has a slope of 1 and a y-intercept of 0.
Plot the given point (assuming that it's NOT on this line).
Draw a line perpendicular to y=x that passes thru the given point. This perpendicular line will be y = -x.
How far is the original point from the line y=x? The reflection of this point across the line y=x is the same distance from the line y=x, but on the opposite side of the line y = x.
Answer:
8.8 pounds
Step-by-step explanation:
There are 7 days in a week, so the daily loss was ...
(28 kg)/(7 days) = 4 kg/day
In pounds, that is about ...
(4 kg/day)(2.2 lb/kg) = 8.8 lb/day
