To find the x intercept, sub in 0 for y and solve for x
y + 12 = 3(x - 9)
0 + 12 = 3x - 27
12 = 3x - 27
12 + 27 = 3x
39 = 3x
39/3 = x
13 = x.....so ur x int is 13 or (13,0) <==
and if u wanted to find the y int, u could sub in 0 for x and solve for y
Answer:
When multiplying a number by 10, move the decimal to the right. Whenever a number is multiplied by 10, the decimal is shifted to one place in the right.
Like : 
When multiplying a number by 0.1, move the decimal to the left. This means the number is multiplied by 
or we can say the number is simply divided by 10.
So, when a number is divided by 10, the decimal is shifted to one place on the left.
Like : 
or 
<span>-x^2 - 4x when x = -3
-(-3)^2 -4(-3)
= - 9 + 12
= 3

Explanation:
The slope can be found by using the formula:
m
=
y

Where
m
is the slope and (
x

,
y

) and (
x

) are the two points on the line.
Substituting the values from the points in the problem gives:
