Hi, today we are solving the question in which the equation for the appropriate dosage for a child of age a is given by c is equals to 0 .0417 d into a plus 1.
00:17
Now to find the slope of the graph of c, we need to rewrite the equation in slope -intercept form that is y is equals to m into x plus v where m is the slope, y is the dependent variable, x is the independent variable and b is the y -intercept.
00:35
So to do this we can substitute this as from above equation we can take it as c is equals to 0 .0417 d a plus 0 .0417 d.
00:53
Now we can see that the slope of the graph is 0 .0417 d which represent the rate of change here slope is m is equals to 0 .0417 d which represent the appropriate dosage of a child with respect to the age of child.
01:17
So we can say that therefore for every one unit increase in age of child the appropriate dosage increases by 0 .0417 d units.
02:00
Now taking the next one, so here we need to find the dosage for a newborn.
02:15
So we can substitute a is equals to 0 in the given equation.
02:20
So c is equals to 0 .0417 d into 0 plus 1.
02:27
So we get c as equals to 0 .0417 d...
