3. Orenda has a total of 41 loonies ($1 coin) and toonies ($2 coin) in her piggy bank. Their total value is $59. a. Write one equation for the total number of coins and a second equation for the total value.
b. Graph both lines and determine the coordinates of the point of intersection of the lines.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
