A ball is dropped from a height of 64 feet. It's height, in feet, can be modeled by the function h(t)= -16t *power of 2* + 64, w

here t is the time in seconds since the all was dropped. After how many seconds will the ball hit the ground ?

cora says she doesn't need to know the y-intercept of a line to write its equation, just its slope and some other point on the l
Nadusha1986 [10]

Answer:

The equation of line with given slope that include given points is                 3 y + x - 20 = 0

Step-by-step explanation:

According to Cora , if we know the slope and points on a line then we can write the equation of a line .

Since , The equation of line in slope-intercept form is

y = m x + c

<u>Where m is the slope of line , and if we know the points ( x , y ) which satisfy the line then constant term c can be get and the equation of line can be formed .</u>

So , From the statement said above it is clear that she is correct .

Now , Again

Given as :

Slope of a line is m = - \frac{1}{3}

That include points ( 2 , 6 )

Now from the equation of line as  y = m x + c

∴   6 =  - \frac{1}{3} ( 2 ) + c

Or, 6 =  - \frac{2}{3}  + c

So , c = 6 + \frac{2}{3}

or,  c = \frac{18 + 2}{3}

∴   c = \frac{20}{3}

So, The equation of line can be written as

 y =   - \frac{1}{3} x + \frac{20}{3}

Or, 3 y = - x + 20

I.e  3 y + x - 20 = 0

Hence The equation of line with given slope that include given points is     3 y + x - 20 = 0   Answer
