A garden patio is covered with grey slabs and yellow slabs. 1/5
of the slabs are grey.
a) Write down the ratio of grey slabs to yellow slabs.
Give your answer in its simplest form.
There are 55 slabs in total.
b) Work out the number of yellow slabs.
yello

A) 1:4

B) 44

There are 11 grey slabs and 44 yellow slabs.

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
