Answer:
Okay so, one pen equals to 25p, one rubber equals to 10p, and Erica bought a pencil, a rubber, and a ruler for 1 pound, which means 25p+10p equals to 35p, and 100-35= 65p, so one ruler costs 65p, so Horace bought a pencil, a ruler and a pen, we know one pencil equals 25p, a ruler costs 65p, and a pen also equals 25p, so 25+65+25 = 115, so 1pound 15 p

Step-by-step explanation:
First find the slope using two points:
m = y/x = [y1-y2] / [x1-x2]
m = [2.5-(-5.5)] / [-0.25-1.75]
m = -4
Find b using one of the points:
y = mx + b
y = -4x + b
2.5 = -4(-0.25) + b
1.5 = b
y = -4x + 1.5
