I need help in question 19 in may/june 10 v 21
I didn't get the question
so first part u r just supposed to sub in values in for t. For t=3: r= 2p + 3(p+q) r= 2p + 3p + 3q r= 5p + 3q

Now, for the second part, it shows 1p = 2 boxes on x-axis AND 1q = 2 boxes on y-axis.
one by one sub in each point. for example for t=3 , r= 5p + 3q. this means go 10 boxes on x-axis and then from there start moving up 6 boxes. wherever u get mark that point. Follow for the same for the rest.

Could i please get help on how to draw stretched diagrams?
so if the question says stretch by a factor of 3 along the x-axis, all points along x-axis will be multiplied by 3. Now, take the example of a rectangle. If u r supposed to stretch by factor of 2 along x-axis. All the x-coordinates will be multiplied by 2.
