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

Tanzania [10]

Answer:

The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit

Step-by-step explanation:

P.S - The exact question is -

Given - Sophia buys an apple that weighs 0.45 pound, a grapefruit that weighs \frac{3}{4} pound, a navel orange that weighs \frac{5}{8} pound, and a pear that weighs 0.5 pound.

To find - What is the order of the fruit from least weight to the greatest weight ?

Proof -

Weight of apple = 0.45 pound

Weight of grapefruit = \frac{3}{4} pound = 0.75 pound

Weight of navel orange = \frac{5}{8} pound = 0.625 pound

Weight of a pear = 0.5 pound

As,

0.45 < 0.5 < 0.625 < 0.75

So, The order of fruit from least to greatest weight is -

Apple , pear, navel orange, grapefruit
