A line contains the points (3,9) and (-1,1) what is the equation of the line?
kirza4 [7]
To find the equation of a line using two given set of points, you must first find slope. To do so, we must use the slope formula:
y2 - y1 / x2 - x1 

In this case:
1 - 9 / -1 - 3 = -8 / -4 
- 8 / -4 = 2 (simplified) 

Now we can use the point-slope formula:
y - y1 = m(x - x1) 

y - 1 = 2(x + 1 )
y - 1 = 2x + 2
y = 2x + 3

In order to make 3x - y = 6 in slope intercept form, we must isolate y.

- y = -3x + 6
Note: y cannot be negative, so we'll multiply both sides by -1 
( -1 ) - y = - 3x + 6 ( -1 ) = y = 3x -6

PLEASE HELP = simplify 3/4(-10+2/5)
solniwko [45]
There are many ways to do this depending on the property you have to use:

If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:

\frac{-30}{4}  -  \frac{6}{20}

Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:

\frac{-150+6}{20}

Now you can just add them together to get:
\frac{-144}{20}

and then simplify your fraction:
\frac{-36}{5} or - \frac{36}{5} 

The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.
