Question

Answer:
Qno 2: Given the line x/4+y/5=1
i)Make y the subject of formula
X/4+y/5=1

Answer:

ii) Find the coordinates of the point at which the line cuts the x-axis.​

Answer 1

Answer:

$\frac{x}{4} + \frac{y}{5} = 1 \\ \frac{y}{5} = 1 - \frac{x}{4} \\ y = 5( \frac{4 - x}{4} ) \\ y = \frac{5}{4} (4 - x)$

Since it cut x axis, so y = 0

then, x = 4

So coordinates of the point at which the line cuts the x-axis is (4, 0).
