General form of the line equation is: y= mx + c 
where m is the slope and c is the constant 
the slope here is given and equal to 3 
so, m= 3 
y= 3x +c 
to get the constant c, substitute with the point in this equation 
y= -2 & x = 1 
-2 = 3*1 + c 
c = -5 
then the equation of the line is y = 3x -5 
y = 3x -3 -2 
y +2 = 3(x-1) 
the answer is (B)

statuscvo [17]

Answer+Step-by-step explanation:

m = man's age

s = son's age

m=s+36

Resolves to: s=10, m=46

So the man is 46 (=10+36).

In 8 years, son is 18 (=10+8), man is 54 (=3*18 and 46+8), thank you.

Stella [2.4K]

Answer:

The number of houses built in Town B is 56.

Step-by-step explanation:

We are given that in 2010, the number of houses built in Town A was 25 percent greater than the number of houses built in Town B.

Also, 70 houses were built in Town A during 210.

Let the number of houses built in Town B be 'x'.

So, according to the question;

Number of houses built in Town A = Number of houses built in Town B + 25% of the houses built in Town B

70 = x + (25\% \times x)

70 = x(1+0.25)

x=\frac{70}{1.25}

x = 56

Hence, the number of houses built in Town B is 56.
