For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut point with the y axis
By definition, if two lines are perpendicular then the product of their slopes is -1.
If we have: 

Thus, the equation is of the form:

We substitute the point:

Finally, the equation is:

Answer:

Answer:
£2121.80 he would have earned £121.80
Step-by-step explanation:
2000 × 1.03 = £2060
2060 × 1.03 = £2121.80
(2 Year's)
£2121.80 - £2000 = £121.80
Okay so 11/4 needs to be multiplied by 2 so that the D match up.
so 11/4 x 2 = 22/8
22/8 - 3/8 = 19/8
The difference is 19/8
