Line y=mx+b has point (0,b).
If you've got poind (0,4) - you can write, that b=4.
So this is line y=mx+4
Now slope. You've got point (1,0), so for x=1, y=0. Substitute:
m * 1 + 4 = 0
m+4 = 0
m=-4
So equation of this line is: y=-4x+4

Papessa [141]

Answer:

My age is 12 years.

Step-by-step explanation:

Given:

Sister's age = 10 years

Let my age be x.

Now according to question;

my brother's age is 1/3 of my age

So brother's age = $\frac{1}{3}x$

Also according to question;

my sister is 6 years older than my brother;

Sister's age = $6+\frac{1}{3}x$

Also given Sister's age = 10 years

hence equation to find my age will be expressed as below;

$6+\frac{1}{3}x = 10\\\\\frac{1}{3}x = 10-6\\\\\frac{1}{3}x = 4\\\\\therefore x = 4\times3 = 12$

Brothers age = $\frac{1}{3}x=\frac{1}{3}\times12=4$

Hence my age is 12 years.
