Y - 9 = 2(x - 1)
This is because the base equation is below:
y - y1 = m(x - x1)
X=1/3
Distribute 8 through the parentheses
8-40x+5=-2+5x
Add the numbers
13-40x+5=-2+5x
Answer: x=1/3
Step-by-step explanation:
Only D, y = 3x + 12 is in slope-intercept form.
For the division part:

But I think your question differs than this..
Am I right?
as your options do not include 1
Area of a circle using the radius is pi*r^2, so:
A=3.14*4^2
A=3.14*16
A=50.24
