Yes - Congruent means identical, similar means identical or in the same scale (i.e. 2x bigger, 1/2xbigger etc)

plot the three points (remember (-2,3) means -2 on the x-axis and 3 on the y). Joing all three points Then draw the reflection of it using the y-axis as the mirror line.

Some function are linear equations, others could be quadratics equation, cubic equations etc. Basically, a function shows the relationship between two quantities

b i) a = 8 000 000 r = 1.2 Pn = 8 000 000 x 1.2^(n-1) b ii) a = 8 000 000 d = 400 000 Pn = 8 000 000 + (n-1)400 000 = 7 600 000 + 400 000n This should help you to do the rest!
