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

Convert 2 Liters to gallons. Use the fact that 1 gal.= 3.8L.

iris [78.8K]

we know that

1 gal.= 3.8L

we can also write as

3.8L=1 gal

Firstly, we will find for 1L

so, we can divide both sides by 3.8

$\frac{3.8}{3.8} L=\frac{1}{3.8}gal$

$1 L=\frac{1}{3.8}gal$

now, we will multiply both sides by 22

$22*1 L=22*\frac{1}{3.8}gal$

$22L=5.78947 gal$

$22L=5.8 gal$

so, option-b.............Answer
